If you want to mine monero then mine at supportxmr, they also provide helpful steps from downloading your wallet, mining software, and configure the mining setting. The minimum withdrawal is quite high at 0.1 XMR but you want withdraw if your balance is less than that but they will charge you 0.001 XMR as fee if i remember correctly. Also don't mine monero using GPU, it's not worth it, just use the GPU to mine something else like ETH.
