Is there any suggestions of bitcoin mining sites using my laptop?
It's going to be not worth it, but there are options available. Firstly, you're going to not make enough to pay your electricity bill increases as a result of your mining activities. Your laptop is going to be overheated and even may damage your laptop hardware. Based on the above, you shouldn't even bother. Just buy bitcoin instead if you want to get into cryptocurrencies. If you insist on continuing, i've heard that freebitco.in has a pretty nice laptop mining feature. You'll get paid in BTC but you're actually mining XMR with coinhive. Still it's not worth it, even though freebitco.in does not take anything from your payouts.
Yes, that's right. Precisely with the use of laptops, it will make us lose because our laptop will be very hot and damaged. If you want to be serious in mining business, you should set up a good computer and a VGA suitable for mining. Or if you want mining to use special hardware like SHA-256, you can set it up. But you must do research because the cryptocurrency you are looking for can have different hardware specifications. And as our friend has told this one, if you do not have enough capital yet, you can invest into cryptocurrencies like Bitcoin and Ethereum by buying and collecting and wait until the price goes up.
