When I trade a token, some part of that token remains. This is what happens when almost all tokens are traded. Especially on the exchange side.
My question is can the whole token be returned? If so, tell me.
Do you mean that when you are trading in an exchange, there will be some small remaining tokens that are not able to trade? Yeah, most exchanges also do this term.
And the numbers of the remaining tokens among the exchanges are different.
It is because of the different decimal to be able to trade set in each exchange.
And some exchanges may also provide a feature where we can convert the small remaining token into their initial token.
Like in Binance, we can convert the remaining tokens into BNB.
BUt, I don't know if all exchanges also provide this feature or not.
Check on the application feature of exchange that you're using.
