Yobit is not that trust worthy of an exchange they have had multiple complains from users who lost thier coin and withdraws stuck and most importantly they have one of the highest fees, compared to others, if you are talking about investing in the Yobit IEO that they have been promoting and runing for some time now, than i would advise you otherwise, because as i said they have a bad reputation so the coin won't do that well and don't trust anyone who is promoting them especially on YouTube because they are paid to say so.
