Miners are using laptops to mine crypto this days, I've seen a whole farm full of laptops only mining crypto, you don't have to mine BTC directly since they require ASIC miners today, check the GPU in your laptop if it's around 6gb video memory probably 1660 gtx will do and download Nicehash to start earning and you will also get paid in BTC
Can you recommend any currency that is profitable to mine on laptop. In this thread I came to know that MASS is the only one that can be mined profitable on normal gadgets. I wish I had mined this currency on laptop when it was not on exchnage.
