I have been using probit a few times but you must be careful with shitty exchange like this. The owner of exchange (team) can change their policy anytime they want. I was able to withdraw my money caused by i was doing hit-and-run trade but I never tried to use this exchange site again. This exchange site is shitty exchange site.

Why don't use MEXC or Bitbns service itself to trade your BNS token? I see that if it's still available on kucoin (maybe)
