Without accounting for electricity how long would a #bitaxe pointed at a pool take to pay itself off?

#asknostr I'm on solar and I could run a bunch of those things 24/7 without hurting my batteries.

Or would it be a better idea to get something else that can solo mine other coins and swap them for btc?

Or just spend the money on buying #btc instead of #mining?

Or is there better low watt hardware for mining btc?

Which pools do you recommend or do you recommend the lottery instead?
