what is the best hardware for mining btc PU or asic ? if it's possible i need some technical details
thnks.
You can't mine Bitcoin with PU or GPU's.
You can mine btc with a gpu. You need to solo mine it.
But the power used and the time needed to hit a solo block with a gpu is not cost effective.
At op. If you want to mine btc directly you need the Avalon 741 from Canaan.io
Or a s7,s9,r4,t9 from bitmain
