But now I am doing it on centralized exchange or trading, to be more accurate I am using binance to trade my crypto into cash everytime that I wanted to.
I never really experience any tax other than transaction fees in cryptocurrency.
That could happen because the tax system in your country is not strict. However it is still possible that one day later you will be asked to provide a tax report based on the money that goes into your bank account.
If you are concern about being monitored or tag on ALMA, then don't send a huge amount in a single transaction try to do it separately with small amounts.
That is only a short-term solution to avoid taxes if you are still using your bank account to receive that money.
