So solo mining with 35 TH\s geta me 1BTC, and there's a difference with pool mining which one is profitable? I mean both obviously produce since there are no electrical fees, but if solo I can do 1btc at a pool with 35TH\s how much will be the winning? Or it only varie with pool hash rate and people who is working in the block? If that is the case which is a good pool to start in so I can get 1btc monthly.

I don't know much about mining, want to know the less expensive most effective rig to produce 1 BTC monthly, since each 10 min there's a block found and the block pays 12.5 btc how much rigs do I need to produce 1btc\month?

How much equipmwnt do i need to.produce 1btc monthly? How much would it take, solo ando in a mining pool. Don't add electricity bills in my country we pay like 0,25$ monthly so there's no such thing as that affecting the profits if there's a way to get 1btc monthly.

Thanks in advance!!
