I'm facing an interesting issue with HitBTC. I cannot put any order. No matter what pairs I'm using I'm getting the same error "Your buy order was rejected" And not because of insufficient funds, just rejected.
Plus I cannot use the trollbox although I have over 0.01 BTC as requested to use the trollbox.
It might be because your account was blocked. Why are you still using a scam exchange like HitBTC?
Try contacting their support but your chances of recovering your account are slim. HitBTC are scammers right from the word go.
