Interesting move from a post-quantum-secure crypto named QRL
It's time to think about what threat Quantum Computers have agains crypto
Will Ethereum 2.0 be safe against Quantum Computers or will there be another update that takes years for that in the future?
Will Ethereum 2.0 be safe against Quantum computers and what about other coins?

$QRL. It's built entirely on NIST-standardized post-quantum cryptography, already running in production. It also provides financial-grade digital signatures and audit trails that remain secure even when quantum computers break today’s encryption. Great potential IMO.
That’s why I’m invested in QRL, and buy ETH and BTC on downturns like this. People be greedy. It’ll swing back up eventually, im literally betting money on it
I think Zcash's private transactions are still vulnerable to quantum-enabled attacks, so I'm not sure why it's listed. Why didn't you mention QRL? It's the biggest quantum-resistant blockchain.
Seven years are an estimation of the whole social-technical process of migration from preparing and discussing the concept until full integration of all users on the final product, like with SegWit and Taproot. Going offline during that process is nearly impossible, though. The 6 million figure includes those that have outgoing transaction (about 4 million), but are not S2PK. Most of these could probably move easily. I wouldn't expect a possible quantum attack this century, but it's always better to be safe than sorry. If QRL can provide a good experiment that can be integrated into Bitcoin's code, that's a good thing!
More like 2 million in total, if really nobody has got the key anymore. QRL doesn't solve the problem of what happens with these, so it is not a viable alternative. It could work as a case study of how to implement something comparable in Bitcoin (as with nearly all development in altcoins). Who estimates these times? A soft fork doesn't cause downtime. Who would endorse a protocol with 140mH/s. It's clearly a case study/experiment for Bitcoin core updates.
There are 6.2M BTC vulnerable in early legacy P2PK outputs and exposed public keys. For these vulnerable outputs, the choices really is only whether allow them to be stolen or freeze them. Satoshi alone has 1 Million BTC where the key is already revealed. Who in their right mind wants to endorse a protocol that freezes coins, or allows them to be stolen and leave the original owner? This is your future of finance? Downtime is estimated at over a year and migration taking up to 7 years. Sorry but no. You have to be quantum secure from genesis like QRL. Bitcoin is a dead man walking.
Buy the QRL dip. Low volume because of the overall lull in the crypto markets and one whale seller pushed it deep into oversold territory. Plus proof of staking is coming within the next 6 months which should also increase price.
QRL has been around for 8 years and standing strong in the midst of the quantum threat. Peter Thiele just got out of ethereum because of quantum threats, Kevin O'Leary recently said institutions should avoid crypto because of vulnerabilities to quantum computers. QRL is the only fully-audited, NIST guideline-following cryptocurrency, and that's why I'm loading up on it this most recent dip.
Even a quick ChatGPT will tell you Algorand is not Quantum Resistant. You have to be quantum secure from genesis or you run into all kinds of problems. 'Algorand’s CTO has publicly stated that while history protection is done, **accounts and consensus are still vulnerable** and need quantum-safe upgrades — estimating they are roughly *one-third* of the way to full quantum security.' There are tons of blockchains coming out claiming they are Quantum Resistant almost none of them are. QRL has been the leader in this space since 2018. Lockheed Martin even filed a patent using QRL for secure communications.
No I'm not part of the QRL Team. Just a guy interested in computers and blockchain.
They either have to freeze/burns coins, or allow them to be hacked/harvested by a Quantum Computer. Those are the only two choices. "QRL has had post-quantum security since 2018. No migration, no downgrade, no governance fight. Why store generational wealth on a foundation with a known expiration date and a painful fix when QRL already solved this eight years ago? - Alami

QRL has the blockchain encryption technology in place to be the long term secure digital fiat. Without quantum security already baked in, you’re just hoping that what you’re holding isn’t a gamble. QRL will be around for a long time.
Been in QRL since the beginning of last year. It's done fairly well for me. That is not an indication of future trends. Actually bought it because it was pretty stable for most of its history and figured the dip was coming, so when the moon rocket petered out I sold everything else and bought it, thinking I could at least protect my "money" from fiat and the upcoming bitcoin drop (4 year cycle thinking). Ended up 4x instead.
You might have heard about it already, but in the near future everyone will be talking about Quantum Computers breaking encryption, and when they do that quantum resistant cryptocurrency will gain a lot of attention regardless of anyone's thoughts on the matter, which will 100% result in wild price increases. The first and the leader in actual day 1 quantum resistance is QRL and it is integrating smart contract support in the near future as it is nearing audit and release (project ZOND)
I genuinely don't understand why more people aren't just buying QRL right now. It's so cheap relative to where it could be if it were more mainstream. The OG quantum resistant coin, without any vulnerability to quantum attacks. Used in a patent by Lockheed martin, around for 8 years...
QRL is poised to go higher. They are one of the best known quantum resistant coins, and as the narrative catches on, I'd expect a quick 10x
Quantum resistance, quantum resistance, quantum resistance. If you don't have a plan, investors with real capital are going to be uninterested. r/QRL is basically the only pure play in the market right now.
Stay ahead of the curve, rotate some into Quantum Resistant Ledger ($QRL)
During one of the worst days in crypto, $QRL +8%. Worth taking a closer look.
Absolutely, QRL is the only real post quantum safe haven with a PQ resistant first block track record since 2016.
QRL is more of a long-dated hedge than a near-term adoption play Until quantum becomes a clear and present threat, most attention stays on usability, infrastructure, and real-world integration If quantum suddenly becomes practical, projects already thinking about upgrade paths and governance will matter more than who was first Being adaptable often beats being early in crypto
I see. But that would be pure gambling. There are few other QR (or pseudo-QR, or fake-QR) coins and their mcap is small (as you wanted), but they were all dying (some had even -95% losses). Only QR coin that is successful is QRL. So, if you have been rekt too many times already, maybe you should start being more careful and not looking for wildfires. Good luck anyway :)
Lol, $200m is too high? QRL's martkecap is still 85x less than DOGE, which is a memecoin. 250x less than Solana. 1274x less than Ethereum. And 7225x less than Bitcoin.
Alright your call mate. I would seriously not fade $QRL.
It's too high already mcap wise. I need to do something different and DCA on this project. It's under $10m mcap. $QRL is 20x that.
Interesting, I haven’t heard of that one. I see it’s testnet only right now, so I’ll have to run it by some people who know more than myself. If you’re into post-quantum crypto, $QRL is a mandatory asset imo. It’s the only one I have rn as all of the others have yet to fully convince me they’re worth the time, and so far that’s been the best play returns wise, too.
I sold all my other crypto and full ported to QRL last July. Saved my ass, I’m up big since then and planning to hold. Extremely solid project, I’m lucky to have gotten in when I did <$1, but I actually just made my biggest purchase since initial position at $2.25 last week. Stop by the Discord if you want to learn a lot more: https://theqrl.org/discord The community is very intelligent, very informed, and very helpful. Top tier shit all around this project really. Very much looking forward to when the testnet for QRL 2.0 updates soon: https://www.theqrl.org/blog/qrl-2.0-building-the-bridge-to-the-next-era/
You mean QRL? Even your "Squirrel" in nick suggests connection to QRL community 👀
It’s the only coin that won’t easily be seized by bad actors and foreign institutions via quantum computing. If you want something long term safe over the next century. QRL is the only option. Nobody will be “leaving their kids” Bitcoin or any other ERC-20 token as that blockchain technology will easily be exploited and broken down within the next decade or two.
QRL +400% past year. Easy choice.
No guarantee but QRL has the highest potential to meet your goal and much more.
$QRL went 5x after BlackRock flagged quantum risk to crypto in May 2025. This is just a start.
QRL value will grow x5-x10 within a year because it will be listed on leading exchanges and will implement smart contracts with POS consensus.
QRL is a rock, it stays as it was.
How stupid do you think it is to invest in QANX or QRL?
That’s good then. I’m not sure what losses I’ll be capitulating as I only have QRL at a very low price at the moment.
Im long QRL and even im surprised at how resilient it’s been during this sell off. A solid base behind it for sure. Reminds me of BTC before it really took off.
Then why are they down over -50% in the last year while QRL, the market-leader in probably quantum-resistant cryptocurrency is up +600% ? Hint: it’s because they didn’t.
It's interesting how QRL has grown significantly after BlackRock flagged quantum risk to Bitcoin (May 2025). [https://www.cointribune.com/en/can-bitcoin-survive-the-quantum-threat-blackrock-has-an-answer/](https://www.cointribune.com/en/can-bitcoin-survive-the-quantum-threat-blackrock-has-an-answer/)
/r/QRL Quantum Resistant Ledger Thank me later or remember when you faded this tip, your choice.
There is QRL (Quantum Resistant Ledger) blockchain which is built on the NIST standardized post-quantum cryptography since their launch in 2018. Externally audited, open source, decentralized and starting to gain popularity this last year. Also there is big upgrade coming this year that will bring smart contracts and proof of stake consensus. I recommend looking into it. They basically solved the problem 8 years ago, so there is no risk for QRL. And it's important to be quantum resistant since the first block, because all the other projects (like BTC, ETH,...) will have huge problems with migration of the current vulnerable coins/tokens/smart contracts/... as that requires manual action from every single user. If Q-day happens before 2030 (some estimations point even to year 2028) then I don't think there is any chance for existing chains to fully upgrade AND migrate their coins to be quantum safe.
No it is really not. First there are other chains that use PQC and more coming out everyday. This is not a moat my dude. Can you DeFi on it? Does it have any use other than Store of Value? QRL is cool but please lets not oversell reality.
Why the hell would you think QRL is a scam? It's been around 8 years, audited, used for patents by Lockheed Martin, never rugged, etc etc If you dont like altcoins that's fine but appreciation is warranted for legitimate projects in an ocean of actual scams
Anyone who seriously and responsibly looks into the topic knows that QRL is the only real choice when it comes to quantum-secure crypto. And the price action speaks for itself.
One concrete data point that often gets missed in these discussions is real-world validation. Lockheed Martin explicitly chose QRL in a quantum-secure communications patent (US20240048369A1). The patent references the QRL blockchain for encryption, key distribution, and secure messaging in a defense-sector context. That matters because this isn’t a whitepaper claim or a future roadmap — it’s a U.S. defense contractor selecting an already-deployed, quantum-resistant blockchain architecture for a real security use case. Most chains are still debating how they might migrate someday. QRL was designed around post-quantum assumptions from genesis, which completely sidesteps many of the coordination and hard-fork risks described in this post. It doesn’t mean quantum attacks are imminent — but it does show which architectures are being taken seriously when the threat model is treated as non-theoretical. That distinction feels increasingly important as migration timelines compress.
QRL is quantum secure from the first block. Also, Lockheed Martin (US defense contractor) has a patient utilizing the block chain for secure data transmission, showing real world use case https://patents.google.com/patent/US20240048369A1/en
Define “crypto scam”, and explain why QRL fits that description.
QRL is not pioneer. MCM running mainnet since June 25 2018 according public available information.
All these Quantum Computing scare monger posts seem always to be from people like the OP who fell for are are shilling crypto scams like QRL. See the OP's post history. 25 YEARS ago, **a 7-qubit quantum computer factored the number 15** and it was supposed to be a threat to breaking encryption algorithms > IBM researchers make another advance in quantum computing, demonstrating "Shor's Algorithm," which can break large encryption codes https://www.wired.com/2001/12/big-blue-takes-quantum-step **(2001)** 25 YEARS later, **1,000+ qubit quantum computers still aren't able to factor the number 21** because it's still too demanding for the hardware > Why haven't quantum computers factored 21 yet? https://algassert.com/post/2500 - **21** - The number that quantum computers still cannot factor with 1,000+ qubit hardware - **115792089237316195423570985008687907852837564279074904382605163141518161494336** - the range of private keys is between 1 and this number which is more atoms that exist in the known universe that dummies think that quantum computers will be able to guess > muh but Quantum Computers are getting exponentially more powerful It is estimated that millions of qubits are required to break ECDSA. But reality is that Quantum computers get exponentially nosier the more qubits they have. That's why a 7-qubit one in 2001 could factor the number 15 but 1,000+-qubit ones in 2026 cannot factor the number 15. **1,000,000+ qubit quantum computers will be exponentially more useless than the 1,000+ qubit quantum computers today.**
CKB is not a pioneer in this area. QRL is. The Quantum Resistant Ledger (QRL) has been running a public mainnet since June 26, 2018, operating for over seven years using post-quantum cryptography. By comparison, the Nervos CKB mainnet launched in November 2019.
Rekeying on Algorand is a migration mechanism, not a magic quantum shield. Rekeying enables migration, not quantum-safe accounts by default like QRL. Until a post-quantum signature scheme is actually used for account authorization, the account remains quantum-vulnerable. Algorand users still face migration pain that every other blockchain that is not quantum secure from genesis will have to go through.
True blockchain longevity requires quantum security from genesis and native crypto agility. QRL (Quantum Resistant Ledger) already delivers this, putting it years ahead of networks that will be forced to confront painful migrations and the burden of legacy cryptography.
Yup, I'm with you here. It's at the end of its useful life. My breaking point was depositing all of the QRL that I had spent the previous 4 years mining at home to TradeOgre literally the fucking day before it got seized. This entire market is still a big unregulated joke.
QRL marketcap is $190million
Why would you name Cellframe who is not fully QR due to significant holdings in ERC20 And not QRL which is the leading QR blockchain and has been so since 2018. Weve seen 2000% growth in value in the last 2 years
/r/QRL does have its quantum resistance built into the protocol mate.
/r/QRL can’t be ignored in conversation of quantum-resistant coins. Probably the best QR project with a live main net rn.
/r/QRL been having its alt season 💅 Up 500% in the past year on growing interest in quantum-resistant coins.
tldr; The article lists the top quantum-resistant tokens by market capitalization. The tokens mentioned include Ozone Chain (OZO) with a market cap of $135.38M, Quantum Resistant Ledger (QRL) with $55.73M, Cellframe (CELL) with $34.48M, ILCOIN (ILC) with $2.57M, and AME Chain (AME) with $1.17M. These tokens are designed to be secure against potential future quantum computing threats, which could compromise traditional cryptographic methods. *This summary is auto generated by a bot and not meant to replace reading the original article. As always, DYOR.
Bitcoin is quantum vulnerable garbage. Quantum Resistant Ledger is the digital gold of the quantum era. QRL = Successor to Bitcoin QRL is the future.
That's great but it's basically like saying I only buy and hold one stock and ignore anything else regardless of how obvious a play it is aka, I don't like money. If you would have put a portion of that maxi funding into QRL at almost literally anytime over the past 3 years while quantum computing was starting to rear it's head you would have x7 today, and that will increase because the quantum narrative isn't going away regardless and attention is one of the largest drivers of capital and speculation. This isn't football, life isn't made of tribes and teams. Quantum computing exists, it's just not at a scale to run shors yet (publicly, we have no clue what closed or nation state labs are doing).
There will definitely be some of that, for example as a result of my own awareness of the almost 100% chance of future quantum computing arrival, I am invested in QRL which uses NIST approved cryptography from day 1 for both security and as an obvious hedge to what will be an ever growing discourse and threat. But my and others personal interests in it doesn't make it any more or less likely to happen. Labs are pouring billions into making it happen and at the state level in eg china it is likely even more (given the advantages it would give a country). Yes some of this is conjecture, but it's far from fantasy, the technology required is absolutely obtainable and I don't quite understand why you think it isn't
There is an easy Solution - QRL. Quantum Resistant Ledger. Compared to BTC and other major Altcoins, were most of you are not amongst the early ones, with QRL you are still very, very early now. And if not convinced own it at least as a hedge. Q-Day will be amazing for QRL holders, nothin to fear about Quantum anymore. Enjoy.
Well, if Q-day happens before Bitcoin is able to upgrade to post-quantum cryptography (which is possible, because core devs and community are mostly downplaying the threat) and fully migrate (which will take years, and 20% of coins are probably already on addresses with lost keys, ready for quantum computers to grab), then you may get massive discount at Bitcoin. Because it would be practically dead. Good info about Bitcoin is on https://quantumrekt.com But at least read also something about QRL (Quantum Resistant Ledger) while you're waiting for the BTC discount :) https://theqrl.org/why
Most people don't know about this, but it will blow your mind. 1) Ask AI about quantum threat to Bitcoin and 99.9% of cryptocurrencies. Realize Q-Day can happen before 2030. 2) Read about QRL (Quantum Resistant Ledger). It is basically only legit project that is safe against the quantum threat. It was launched in 2018, decentralized, open source, doubly audited, using NIST standardized post-quantum cryptography since genesis. And with big upgrade coming soon. You can start at https://theqrl.org/why 3) ... 4) Profit.
just buy QRL. The only real quantum secure crypto. And also XMR.
QRL 10 steps ahead :3
Post is by: jkl2035 and the url/text [ ](https://goo.gl/GP6ppk)is: /r/CryptoMarkets/comments/1qa5cjf/qrl_one_of_the_most_underrated_highconviction/ While most people are only looking at BTC, ETH, and SOL, QRL has been quietly building around a narrative that could become massively important in the coming years: true post‑quantum security on its own Layer‑1 chain. Why QRL looks extremely exciting in 2026: Zond upgrade incoming: The planned transition from PoW to PoS (Zond) is a major technical and economic turning point – more efficient, more attractive for stakers, and more interesting for institutional players. Potential Tier‑1 listing: After a successful Zond go‑live, the probability of a listing on a major top‑tier exchange increases, which could significantly boost liquidity, visibility, and access for new capital. Perfect fit for the current narrative: The market is focused on “blue chips” like BTC, ETH, and SOL – exactly those discussions about security, scaling, and longevity open the door for a project that has been designed with quantum‑resistant security from day one. Real differentiation, not just buzzwords: QRL uses proven, research‑based post‑quantum cryptography (XMSS) on its own chain, not just as a “marketing tag” slapped onto a standard token. Asymmetric risk/reward profile: Small market cap, highly specialized use case, clear roadmap catalysts (Zond + potential listing) – the same kind of setup that has often produced outperformers in past cycles. If 2026 turns into the year where security, sustainability, and institutional adoption move into the spotlight, QRL’s quantum‑resistant infrastructure sits right at the intersection of that narrative. Not mainstream hype yet, but a setup that could quietly become very explosive. Not financial advice – but definitely a project worth looking into now, before everyone else does *I am a bot, and this action was performed automatically. Please [contact the moderators of this subreddit](/message/compose/?to=/r/CryptoMarkets) if you have any questions or concerns.*
BTC & ETH is fine - I‘d add a 20-30% bet component like quantum Token (e.g. QRL, MCM, Abel), Identity projects (WLD) or similar - just for the fun…
Quel était votre raisonnement derrière cet investissement ? J’en ai acheté pour me familiariser avec le concept de l’informatique quantique avant de mieux comprendre… Maintenant, je n’investis plus que dans le BTC, l’ETH, le SOL et quelques micro-projets purement quantiques sécurisés comme QRL, MCM et ABEL.
QRL is the next big crypto long term. It’s not some shit coin. QRL’S skeleton is designed to prevent quantum attacks. It’s the only coin that has been battle tested and has had 100% defense rates. Quantum computing is advancing so fast it’s expected to start attacking crypto in the next 5-15 years. Bitcoin has the ability to fork to a quantum defense in the next 5-10 years but legacy wallets/ lost wallets will still be vulnerable to the attacks because it requires moving the BTC to a new wallet that is quantum resistant. This includes Satoshi’s wallet containing 1 million BTC. It’s estimated that 3-4 million bitcoin are forever out of circulation due to being lost. (Including Satoshi’s wallet.) (for example the guy that had his old computer thrown away by his wife with the computer having 8000 Bitcoin on it.) This means nearly 20% of all of Bitcoins supply has the possibility of flooding the market even if BTC successfully forks before it gets attacked by quantum hacks. The world’s largest weapon contractor has implemented QRL into patents. Lockheed Martin uses Quantum Resistant Ledger (QRL) technology, specifically its post-quantum blockchain, for secure, future-proof data communication and encryption, protecting sensitive defense information from threats posed by future quantum computers.(Source Google) QRL is currently around $2.75 USD/Coin. It is not listed on major CEXS at the moment except for MEXC and a couple others making it difficult to purchase. Project Zond is coming to QRL January 15th 2026. (Hard fork). From my understanding QRL is taking the guts of Ethereum and using them as its own. Upon the release of Project Zond, QRL will be able to go live on all major CEXS. Binance, Coinbase, OKX, Bybit ECT.
I don't have answer about XRP, but if you want to know about something unique and extraordinary, that will soon (possibly in few years) negatively impact 99.9% of cryptocurrencies - including Bitcoin, Ethereum, XRP... - then read something (or ask AI) about quantum threat and Shor's algorithm. Then you will eventually find peace in the existence of QRL = Quantum Resistant Ledger cryptocurrency. Somehow it's still unknown to many, but important to be aware of. You can quickly learn about the whole topic here - https://www.theqrl.org/why
QRL is the shelter from the coming quantum storm. QRL has been quantum resistant from the first block since 2018.
I'm unable to chase all the new hyped projects that will die soon after anyway. I can't time the market to enter and exit at correct moments. I needed to find some quality project with strong fundamentals and long term vision and usage. I found the Quantum Resistant Ledger and I now I can't even bother looking at any other project, because they are all completely insignificant compared to this. It's possible that in few years (expert's opinions vary, but it looks like it could really happen soon) quantum computers will be able to break the classical cryptography that 99.9% crypto currencies use for their security. Including Bitcoin, Ethereum, Solana,... including all the ERC20 tokens on those networks... EVERYTHING is vulnerable now! (ask AI about Shor's algorithm) Everything except QRL. QRL was created with this upcoming threat in mind, and their mainnet launched back in 2018. It's completely based on post-quantum cryptography (recently standardized by NIST) which is secure even against the quantum computers. There is no other project that comes close to it in terms of security and quality, and so it is starting to gain recognition. Additionally there is big upgrade coming this year, which will introduce EVM-compatible smart contracts and transition to Proof of Stake. I really recommend you to learn more about this project and the quantum threat - and what that means to all other cryptocurrencies. You won't be able to look at all the classical cryptocurrencies the same way anymore.
Bitcoin is quantum vulnerable garbage. QRL - Quantum Resistant Ledger is the digital gold of the quantum era.
Check out QRL. Quantum Resistant Ledger!
Think this is one of the Most relevant topics within crypto for the Next years, I personally Hedge my BTC/ETH/SOL stake with some projects which are already quantum resistant Like QRL, MCM & ABEL
QRL is up 350%+ this year alone.....it's not market sentiment. Its the market switching from coins with empty promises to coins with the future security standards in mind.
QRL is the only proven quantum resistant chain with mainnet up and running since 2018.
Don't invest in yesterday's coins, look forward to tomorrow. What might people be buying in droves or speculating on in the future? No it's not AI, that was yesterdays, the answer is quantum safe cryptocurrency. The closer a quantum computer gets to running Shors algorithm the more people will speculate and buy quantum resistant tokens, the more people speculate the higher the price will go, and the first to do this, and the likely leading quantum resistant cryptocurrency of tomorrow is probably QRL due to being the first mover. You don't have to believe a quantum computer will arrive tomorrow for this to work, you simply have to believe that quantum computing breakthroughs will continue to appear, china will continue to shake big tech weakening the AI bubble and advances diminishing non-quantum resistant cryptocurrency confidence, which it will. Is QRL overvalued or undervalued today? No clue. But I have it as my largest hedge bet if my more traditional portfolio tanks and it's doing exceptionally well

Yes there is QRL will be the main one. That is the next Bitcoin imo. I mentioned the other ones as they are still early. But QRL has had over 10x gains in one year. As with any investors you have to do your own research. The more you know the more you'll be able to predict the future and land those investments better. Unfortunately Quantum is difficult to understand. It doesn't mean that it won't change the world though. Just because I don't know how a fridge works doesn't change anything.
BTC+ETH should always be the backbone of a crypto porftolio, but I can also recommend the currencies below. Monero (XMR) --------------- Monero is anonymous, peer-to-peer digital cash. It has the highest level of privacy of any cryptocurrency, rendering all of its transactions totally untraceable. It also has an adjustable block size, allowing it to scale in high network activity. It has a tail emission of 0.6 XMR per block. Yes, this means it is slightly inflationary, but with the rate of inflation tending to zero over time. I would not view it as a "store of value" - it is meant to be used as anonymous P2P cash. However, investing in it could still be a good idea as it has a strong use case, and people will always value privacy. Quantum Resistant Ledger (QRL) ---------------------------------- Quantum computing is a real threat to the cryptography used by almost all cryptocurrencies (elliptic curve cryptography). How soon this threat will materialise - no one knows. What can be agreed on, however, is that the treat is real and one should prepare for it. That being said, almost none of the cryptocurrencies are currently quantum-resistant. QRL is fully quantum-resistant, and has been from its inception. It uses XMSS and will soon migrate to SPHINCS+ (if I'm not mistaken) when upgrading to project Zond (which will allow smart contracts). Over the past few months it has had a good bull run, likely reflecting the sentiment that the quantum computing threat is starting to become a greater worry. Bitcoin Cash (BCH) -------------------- BCH was created as a fork of BTC in an attempt to uphold the original vision of BTC as an electronic, decentralised, P2P digital payments system. It did this by increasing the block size, allowing for much higher throughput. It also improved its difficulty adjustment algorithm to a per-block difficulty calculated as a moving average, rather than the 2016 block average used by BTC. Whether you agree or not with it "upholding Satoshi's vision" does not matter - it might be good as an investment because it is identical to Bitcoin in all the ways that matter and could continue to gather interest as time goes on. Solana (SOL) -------------- Solana is an extremely high-throughput blockchain with cheap payments that supports smart contracts. It has become a hub for decentralised finance (DeFi) and also memecoin culture. Its use case is strong and we might see it have bull runs in the future. BitcoinII (BC2) --------------- This is a very new coin and I cannot in good faith recommend it as a "solid investment", but I mention it all the same as there is a chance it moons. It is, essentially, "Bitcoin, re-launched". It is pretty much identical to Bitcoin, but was relaunched in June 2025. It exists to give people a "taste" of what Bitcoin was like back in 2009-2010, **not** as a competitor to Bitcoin. It is not to be confused with BTC2.
QRL - Quantum Resistant Ledger. This is First Quantumcurrency ever made. QRL is the digital gold of the quantum era.
It is cool to see QRL getting closer to their EVM live network because expanding compatibility with existing tooling can make a project more accessible and useful for developers and users. When teams work toward broader ecosystem integration it shows ambition and helps bridge gaps between different blockchain communities. At the same time I also think about ways to participate in the blockchain space that are tied to real world economic value and not only to protocol upgrades or developer narratives. Platforms like Fractionvest io offer tokenized fractional ownership in real world assets such as property or energy projects which gives a different type of exposure that connects digital innovation with tangible value.
Quantum threat narrative growing ever stronger. Buy QRL.
QRL is up +210% this year. What are you talking about?
QRL has been quantum resistant since 2018, and is by far the best hedge against the coming quantum threat.
Bitcoin is obsolete and a dead man walking. QRL- Quantum Resistant ledger saw this threat almost a decade ago and is the digital gold of the quantum era. You have to be Quantum Secure from gensis or you're screw'd. Trying to retrofit post quantum signatures onto and old slow blockchain is like putting lipstick on a pig.
QRL is also doing extremely well, but for different reason - quantum threat. As it's only real project that is post-quantum secure since their launch in 2018. So it's actually interesting that Monero is doing this well, considering their privacy can be broken by future quantum computers. In case of ZCash they can even create new coins from thin air, yet they also have relatively good price. Strange.
