What is the worst exchange you have ever used or come across??

For me Bithumb...they wouldn't let me withdraw my money. I got it back in the end, but only after showing them that I was posting everywhere about my terrible experience and letting them know it was only the beginning... and that I wouldn't stop until i got it back.

How about you? and why?

Actually there are many of them that had rendered very poor services especially customers trying to withdraw funds from these exchanges. I have also heard of complaints from people about their inability to withdraw their coins from Latoken exchange, though some of these withdrawal issues seem to have been resolved, there others exchanges that are full of shits.
I think for me, i have not experienced any bad exchanges, but to know more about these exchanges, it good to check their reviews or go to cryptocompare to check these exchange reviews before using them.
