Only large profits are relevant, CPFs with small profits do not suffer from this problem.

Can someone who fully understands this market tell me how much tax I will have to pay when selling my crypto here and withdrawing it, in addition to declaring income tax? I've seen people saying that when withdrawing, you pay 2 to 20% to the bank, and in IR you pay 15% on top of the profit in foreign brokerages. I thought that up to 35K in profit there was no IR. I also thought that the purchase and sale needed to be declared annually, but apparently it is up to a month later. Can someone explain this please?
