I mean, neither of those are smart things to do but I am curious how deep Binance actually goes in their investigation.
They are probably going very deep with investigations now, since they had to pay big fines recently and CZ was almost arrested, but he probably made a deal to pay over $4 billion.
I don't understand people who are still using centralized exchanges, they can always ask you this questions and freeze your account even if you have virgin-like coins.
Anyway, I would not blame Royse for this decision, he is in tricky place right now.
That's not Sinbad mixing address but the address Royse777 is paying participants from.
It is a problem if he is controlling keys for that address, but they probably added it because of connection with original sinbad address.
