So for i understand from your writing that you lost money while trading over Yobit ? It's so normal when you couldn't know how to trade correctly and you might lose with wrong strategy you used. There is no issue with Yobit as i think i had trade there and when i get my balance to refunded and i took this and there won't any issue so far i remember. The things are not related to scam i think. If it's not that what i understand please explain in better way.
