When you send a lot of ETH or USDT to a big exchange like Kraken, do they care if its come from a smaller non kyc exchange like Blofin? Do they care if it came from a bridge?
They care that’s why they are regulated and implement KYC to all their customers. You should use decentralized exchange if you don’t want any check like this.
@omegastarscream said above is correct so don’t risk your money if you knew that your funds came from shady origin/tainted.
I’m not sure what exchange Biofin is but it’s safe to avoid all CEX.
