What are the specs of the computer for mining, and what software should I use?
Thanks in advance.
Any CPU will do but in GPU the minimum would be GTX1050ti up to GTX1080ti for Nvidia cards while RX480 up to RX Vega cards. Though you can't just mine bitcoins in that hardware because of the difficulties and traffics so better mine on low difficulty altcoins like Monero or Zcash. That's all and also be watchful on your electricity bills. So better plan ahead.
