It seems now days there are only a few cryptocurrency's that we can mine with decent cpu's. One of thoes is XMR or Monero as alot of people know you can mine with your Cpu quite well. Now I found this website that is legit, and you mine XMR though your web browser, like coinhive and whatnot. But they thing is they give you Raiblocks! www.http://raiminer.com/
You can basically mine the unminable because Raiblocks are not mineable. This is mining Monero and giving you it in Raiblocks instead, handling the conversion on the backend. You can mine and withdraw every hour!
The minimum withdraw is only 1uxrb, and that is like 0.000001 or something so for example you can hit that in just a minute or 2 with a fast enough cpu!
Now if you need a Raiblocks wallet, look no further than the RaiWallet, its a nice web wallet, and you can use it to send your mined coin to. I have done multiple transactions now and never have had an issue!https://raiwallet.com/
