To be honest if you looking some like minexbank from minexcoin well you can just invest like masternode coin. for the masternode you can use some service masternode example like Wire Coin they partnert with some project for service masternode coin you can get a percentage from masternode
I heard about this project. And frankly speaking in general, very much, both good and bad. But I managed to earn a little on this project, because he really had a serious growth. I bought it and sold it in a week. I generally had enough.
