depend on ur hardware but i dont recomend in general using personal PC fpr that

Bitcoin is currently mining with asics . u can theoritcly use graphics cards or even processor to mine but its not worth it at all !

anyway if you have AMD graphics tray ETH and XMR

if Nvidia its better to mine Zcash

finally if you want to tray mobile phone mining . there is intersting coin for that named ETN search google play store for its miner and its not actual mining its just simulate .

good luck

if you manage to get ur temp below 75 c (better below 70) while mining . there is no risks its like gaming .

i have 6 x AMD RX 580 mining rig working since 14 months perfectly
