The least amount of information you need to provide is to actually let people know which country you are from or what the tax regulations are in your country? If your plan is to outright evade taxes that you know are usually due, then asking around in this forum in public is probably not the best way to get the information you are looking for, let alone anyone sane would feel the urge to answer in detail.

In some countries taxes are due on winnings from gambling and then some taxes are due on gains from selling the crypto. It depends. But if the taxes are low on gains from gambling, paying those taxes and then immediately sell the crypto should not go hand in hand with more taxation under most regulations as the money you hold in crypto has been taxed already so to say. Unless you hold the crypto for a while and you realize gains from holding the crypto itself. That's the second case then.
