Hello everybody,
I discovered the service
https://www.nicehash.com/ They rent computational power. I would like to use it with miningpoolhub.com.
I've tried and started it and invested 0.05BTC on mining Monero, without putting any limit (in GH/sec)
I didn't see the point of putting a limit, in fact the quicker the better?!? But I guess I missed something...
Indeed miningpoolhub.com only gave me 1.27 XMR in return, while 0.05BTC is worth more than twice than that.
What did I do wrong? What's the problem?
Any suggestion about using
https://www.nicehash.com/ in combination with miningpoolhub.com?
Thanks a lot in advance for any answer!

Mining is estimations and luck. You should rent for hours/days at slow speeds. You are unlikely to gain anything though; if you want to convert BTC to XMR then I recommend using an exchange.
