With difficulty at all-time highs, does solo mining with ASICs even make sense anymore? Has anyone here a solo block in the last year?
Yes it is still worth it to try, moreover the power draw is very limited, my advice is never use large device to solo mine, the likes of S19 might be a bad idea because of power draw, but smaller devices are worth it, because it is like you are paying zero electricity fee.
Some miners uses 25watts, and some uses 100watts - 140watts and so on, these power consumption is something you won't bother yourself about, it is the type you can plug in and never look back again.
Bitaxe miner solved a block some time ago, I think in the past week and people are still buying this small device to try their lucks, they are way better than USB miners already.
