Minexcoin is a good project, their unique algorithm is to stabilize the volatility of price. And this Minexbank is an opportunity for you to get interest from your parked coins, you don't need to make deposits or what so ever just like investing on a common website, you will just need to sign a message of your receiving address and here you go you are now register to Minexbank. One more thing is their support, they are very active on helping and answering your questions when you contact them either here in the forum or in social media account.
Sounds cool. I like that their support system is good. You can always tell when a company has a good support system they probably also have god service, and good functionality because they put the customer first.
Don't trust them too much though because as well all know, most ICOs turn out being scams!
