Binance is really proved to be the most annoying market place I know! They will do everything to steal your coins!
It is sometime now, that Binance would not let you trade your last coin quantity. For example, when you buy something, they will of course trade their fee as they should. But... because of the fee they keep if you have even 0.99999, you are not allowed to trade that quantity! If you have for example 7.9999 you can ONLY trade 7 coins!
Before, they did that only with the cheap coins that this could be ok. But now they do it with coins that cost even 5$,. If you have many coins like me, you have also many .9991, .995, .997 etc.
The only reason this is happening, is to steal your money or force you to buy their BNB shitcoin! Stealing so much money from million people or force them for the BNB shitcoin, gives great profit for them in exchange of screwing the users.
And they want to be called the best exchange market? In the end even Huobi will get bigger!
It would be better for you to move to other reputable exchanges like poloniex, bittrex. I know that bittrex does have some issues but certainly not like this.Nowadays,there are lots of new exchanges coming day by day and people deposit their bitcoins in such exchanges without even analyzing their reputation and whether they are legit or not.
