Recently I wanted to withdraw a Dog coin and was unpleasantly surprised!!! The incredible commission for the withdrawal of 100 coins made me not do this and sell the coins I bought. I am sure that the exchange makes good money on this. That's right, no one canceled the price increase, especially when Elon Musk became the culprit.
I hope this is a lesson, of course, if no one knows like you did, I hope others don't do that, but whether @elonmusk's influence really affects it, it could become a reality. I don't think I like @elonmusk's style and way of looking for profit only for his own benefit.
Regarding HitBtc, as far as I know, I have used it, and at that time there were many people who got stuck, but it could be solved, even though it seemed a bit slow, so something was missed and it was not paid.
