Don't think many trade from the wallet. What we provided was a much better GUI level trading. We are not removing it due to lag. Only the Bittrex exchange lags on it. Everything else works fine. But we haven't received any input from users using the built-in trading. So we felt it is just an extra baggage.
Well if no one is complaining about it, just leave it as it is no?
Ok. If you guys wish it to be there, we will leave it as it is. Also, in wallet trading is more secure than using a web browser.
