Advice about binance P2P and banks

Hello, I am doing p2p in some centralized platforms (Binance), I just lately began to move excessive volumes akin to 60Okay USD each 2-3 days. The started to ask the place the money is coming from, I have no replied since banks in my country aren't crypto friendly, some suppliers of crypto that I have, (additionally they do p2p) began telling me "You have to create a enterprise account and begin justify the transactions of selling/shopping for crypto by creating invoices for providers", my question is, will this no carry a authorized problem? I mean i do know just isn't unlawful mendacity to a bank, but if they do some type of due diligence that may give me some troubles in the future?
