For me, yobit is the exchange that feels like it can scam me out of my money anytime, although they have never done that but it still feels the same. The customer service is very poor and most of the times they don't even respond to the tickets created, after about 4 to 5 days average time they respond to the tickets that were created. The coins listed there are mostly dead coins or mere pump and dump tokens that are to scam the newbies off of their money, rest the UI isn't that responsive in many low end devices as compared to other more trusted exchanges.
