I find it a bit suspicious that you made a withdrawal after each win, and that you then made a deposit again.
Why would you find it suspicious?
Isn't it a smart practice you, I and many other members keep preaching about in regard to avoiding storing one's funds in a centralized or custodial service?
Deposit ETH withdraw USDT, deposit USDT withdraw ETH, deposit ETH withdraw USDT. The amounts were not like $100 or $200. It may look like using them as mixer although I don't know how risky those bets were. Casino's are not meant to be a mixer. Obviously all these are guess from us.
If it looks like money laundering, why would anyone mix usdt and eth? they're both my hard wallets with the same address. yes, my usdt and eth addresses are the same.
