How to choose
Hashrate vs. electricity cost
Higher hashrate means better odds of finding a block, but it also means higher electricity bills. Calculate your breakeven point: if you're paying $0.10/kWh, a 234 TH/s S21 Pro costs about $8.40/day to run. Make sure you can afford to mine while waiting for a block.
Solo mining odds
Solo mining is a lottery. A single S21 Pro has roughly a 1-in-2.8-million chance of finding a BTC block per 10 minutes. But when you win, you keep the entire 3.125 BTC (~$300k+). Lower-difficulty coins like DGB and DOGE give much better odds for solo miners.
Home mining considerations
ASICs are loud (70–80 dB) and produce significant heat. If you're mining at home, consider a Bitaxe or Goldshell Mini-Doge for quiet, low-power operation. For full-size ASICs, you'll want a garage, basement, or dedicated space — or consider hosted mining.
