Advice about binance P2P and banks

Hi, I am doing p2p in some centralized platforms (Binance), I lately started to maneuver excessive volumes akin to 60Okay USD each 2-3 days. The started to ask where the cash is coming from, I've no replied since banks in my nation will not be crypto friendly, some suppliers of crypto that I have, (additionally they do p2p) began telling me "You might want to create a enterprise account and begin justify the transactions of selling/buying crypto by creating invoices for providers", my query is, will this no carry a authorized challenge? I mean i do know is just not illegal lying to a bank, but if they do some sort of due diligence that may give me some troubles in the future?
