You can use Nicehash to do the same and I can bet you ll get much better results. Still, CPU mining s been dead for a long, long time. There s no way you can make anything here unless you have completely free electricity.
No, it's mining XMR which is a CPU mined coin. It turns a profit with most modern desktops. I've tested it and calculated the figures rather than just assuming.
I do not think this is worth it because it will cause to harm your computer, CPU mining for me is not profitable specially it consume lots of electricity and if you are in the country which the rate of electricity was too high do not try this and if you really want freebitco.in just claim only in their faucet and not to mine. I try this in just one day but I only get small satoshi which is very far on my expected satoshi to receive but if users really want it just go and take the risk but still for me it’s not recommended.
I think browser mining will harm the computer hardware. It needs a specialized hardware for mining and also they are giving a very low amount to the people who are mining through the browser. I am not getting one thing clear how can a company pay 100% through browser mining to the participants who are doing browser mining.
No, it won't harm your computer. Processors are quite good at processing without hurting themselves. They have safety features to reduce the frequency when they near their temperature limit and cutout if that doesn't work.
Mining XMR and exchanging it for BTC is profitable and freebitco.in are passing on all profits to their customers, it's a bit of a gimmick to get more people using the site, but hey why not?
