Not trolling. I'm just exposing this is how rounding works in many scenarios. Even when you pay taxes at your store.
OP was selling, this small transaction rounding problem doesn't happen if you are buying BTC, only if you are selling in small chunks.
Just try it on the exchange and you will see.
Yea you're not getting it.
Even with rounding, when you put an ask / bid in you can determine your fee.... and make decisions based on that knowledge. Take the TOTAL amount, multiply by the percentage, then round. The fee should be accurately calculated. This is how it is with other exchanges.
That's not the case in this example. When OP puts a sell order, his fee is at the mercy of buyers... which is inconsistent with how other exchanges behave. This is definitely a flaw.
