What do you mean make trials for withdraw? The last time i did a trade on binance was a while back and when I did this, it was me immediating trading a coin for another coin for whatever the current price was. I am not doing like those market or limit orders where i buy or sell when it hit a certain price.
So i could still test it when doing it instantly? Example imagine trying to sell altcoin for btc at a certain price. Like when i click sell altcoin for btc... will it ask for confirmation or does it do it automatically? Similar to like how you make a wager... does it ask you are you sure with your selection? Does binance do this?
