IQ Option returned my deposit but blocked the profit I tried to withdraw

I traded successfully and requested a withdrawal, but the process changed when I tried to take the profit out. I was given general references to terms and conditions without a specific explanation of which trade or rule caused the money to be withheld.

Bonus offers and account rules should be read before depositing, not after a withdrawal is rejected. Keep a copy of the terms that applied when you registered, avoid making trading decisions based only on a promotion, and request a detailed written explanation for every balance adjustment.
