... or consult a lawyer on how you will pay the tax for yournmoney to save you from trouble.
OP, this is the best advice you've ever been given. It is good to come to the forum to gather opinions and see if there are people who have been in a similar situation to yours, but at the end of the day, I have seen several threads of this style, and in the end it is best to consult with a lawyer who is a specialist in crypto taxation. With the money you have withdrawn, you have enough pay him for a consultation or even have him prepare your tax return for you. Think of the money you pay him as an investment.
I certainly agree with this as well. A lawyer from your country would help because we have different taxation laws in each country. Some of us are obliged to pay taxes from gambling profit and some are not unless we declare our winnings. You better ask for professional help from a lawyer so you'll be able to take legal and wise action regarding your situation.
