I am mining with CPU Ryzen 1700, i have asked support of minergate, they told me mining 1 XMR can take a month wow, i didnt know that this takes so long but ok
wow if that's the time frame to have at least 1 monero you should calculate the actual expenses and risk of messing with your device
its maybe much prefer to find other coins or other miner like nicehash or try to find the actual thread of some profitable coins like
zcash or eth.
