NerdQAxe ++ is my favourite solo miner right now, can't go wrong with 80watt power draw, I can run this for many years to come unless the miner dies on me, I can't tell if those Avalon nano are open source and this is where I have problem with these miners.

Are miners selling their Bitcoin yet? I can't find a data that they are doing this right now, I think the price for these miners will still dump hard once Bitcoin goes down to 30k or 40 in the next bearish year.

I feel that's the perfect time to get this miners for discount, home miners might not be profitable anymore but it's fun, I can run one for the next 10 years to come and maybe, just maybe I can hit a block.
