HydroMiner Review

MoneroHash is a US mining pool created solely for Monero mining. Since 2014 it is run by a single person. The fee is 1.6 and a part of this amount is given to open source developers. The payouts occur every 24 hour (in case if the threshold is reached). There's an option to send the mined coins straight to the exchange wallet. It saves users some money that could be spent on transaction fees.
