this project is locked on maintenance on bittrex since months, yobit is a scam exchange so stay away from it
It's sad to see it a little. But the idea is if you work for Yobit carefully, it is possible and not bad to slip and do some work.
I do not know for whom, of course, everyone has different experiences with this exchange.
I used this exchange and did not get a negative experience. Perhaps because the number of coins was not very large (not more than $ 1000). But on the exchange you can deposit and withdraw USD
