How do you cash out your crypto?

I like to use legal gambling sites. It seems like they all accept crypto deposits, but are there any that accept this without a rollover requirement?

I would like to deposit about $1,000 in USDT, but I don’t wanna gamble all of it. I would only like to gamble about 20% of it and then cash out my remaining deposit (and leave my winnings on there to play with.)

I understand that the deposit promotions have crazy rollover requirements, but are there any sites that have minimal or no rollover requirements if you deposit without choosing a promo?

If you know of other methods of cashing out your crypto without the government having to know every little thing that you do, I would love to know. 😂
