I'm considering buying a used, $100 laptop to mine PandaCoin, DogeCoin, PepeCash, HempCoin, and other alt-coins. I've never mined before and I'm curious to know if it's worth it. Is it possible to make a profit? If not, can I at least make my money back? I would appreciate any advice you can give me.
I don't know the exact specs because I'm not sure which computer I'm buying but it's going to be a 2-3 y/o model and is probably going to be running windows 7. I want to mine for 12 hours a day but if my pc overheats to the point where I think its a fire hazard then I will reduce mining time. I'm not too experienced with any of this stuff, so I'm unaware of the terminology or what I should be looking for. I'm just really interested in the idea of decentralized currency and I want to (1) help out the community by keeping up the blockchain (2) get some coins for myself so I can start interacting with the community and start spending cryptos.
