I bought coins on Yobit. The wallet then went into maintenance. Now I can't get my coins out. Yobit is a bad place to do business. They set up traps.
Welcome to the party, this isn't a new thing they are used to do this so often and we're used to it. they do this to avoid letting people to do arbitrage trading to be able to do it themselves, that's just a bad practice in business. but did you actually check to see if the wallet was already in maintenance before you bought the coin? because sometimes when people buy something they will face problems since they never check everything before spending their money.
They are a heaven for shit coins and pump and dump devs.
They are too holding ponzis, yobit coin being their largest one and are not a real exchange to be trusted with.
