I was tempted to open an account there days ago because one token listed there has a price more convenient for me, but now I think I will wait to see how the problems outlined in this thread will evolve.
They are fine, sometimes it takes time for transactions but that happens on any exchange. I mean I don't know if they are going to ever scam or not, I wouldn't put more than 5-10% of my money on their hands.
We can't easily say that exchanges are a scam simply because you incur a problem we must understand the volume of transaction per minute but yeah we must very careful when putting your hard earn money. Personally, I believe the exchanges are not a scam and will never be but still hope for a better services and lower fees in the future.
