GPUs mine altcoins like ETH. You can trade altcoins to get BTC.
With a 7 GPU (GTX 1060) mining rig hashing at around 140MH for ETH (~1.25 ETH monthly), it will take you around 10 months to gain 1 BTC worth of ETH. This is based on rates as of writing.
Good day, im just want to know if they have miner for android mobile phone ?
Thanks.
You will kill your phone by mining on it. But if you want to, there is "MinerGate" for mobile.
