I actually use Odroid HC1 (discontinued) as bitcoin, ln, and tor node. Only disadvantage I see is that it has only 2GB of RAM... I am thinking to upgrade to QUARTZ64 from Pine64, just I'll wait until it will work with default Debian kernel: https://pine64.com/product-category/quartz64/
alright boys, i've been scouring twitter for the crypto gems, that people who don't want to play it safe are going for. and these are what I've found. please give your thoughts (DIAMOND HANDS ONLY, NO PAPER HANDS): FTT, ROSE, AKT, QUARTZ, QANX, KDA
Check out QUARTZ (Sandclock), defi 3.0 with up to 60% APR on stables. Price is directly correlated to TVL with the platform launching in January. 50m market cap. METIS, L2 optimistic rollup with close ties to Vitalik. His mum is actually on the Metis team. They are implementing a lot of features that vitalik has outlined in his future plans for Ethereum. Think MATIC but better. 125m market cap.
