Binance has some disadventages. If you wan't to place an order using their API, you have to check that the amount, price and total cost fit certain parameters, which are too restrictive. For example, you can never place an order for buying 0.011 ZEC, cause the maximum precision is 0.01. So they just truncate your order and you only buy 0.01 ZEC minus their commission (If you don't hold BNB). If you have 0.011 ZEC in your account, there is not way to sell everything, because the maximum precision you can set is 0.01 ZEC.
