Several time using probit for my exchange selling coin from bounty campaign still success and do not have problem with deposit and withdraw, always faster when send my coin from etherwallet to probit address and take few minute withdraw from probit to my address exchange other wallet, I like this wallet.
I think maybe the OP did the wrong things that were might sure if its statement is true or not.
Because, as I can see with the other users of Probit they don't have a problem using except to the author
of this topic. What do you think?
The OP didn't complain about the exchange feature like trading or withdrawal, The OP clearly says he made a mistake on deposit for not putting a
MEMO which is very important on exchanges, usually the exchange use only one wallet on this chains BNB, XRP, EOS. So to identify your deposit they need this MEMO and the OP forgot to put it on his deposit and his problem is the exchange response to recover it, he is waiting for it.
Some low level exchange like this has really poor support.
