Advice about binance P2P and banks

Hi, I'm doing p2p in some centralized platforms (Binance), I lately began to maneuver excessive volumes akin to 60Okay USD each 2-3 days. The started to ask the place the cash is coming from, I've no replied since banks in my country aren't crypto pleasant, some suppliers of crypto that I've, (additionally they do p2p) began telling me "You have to create a enterprise account and start justify the transactions of promoting/buying crypto by creating invoices for providers", my query is, will this no carry a authorized challenge? I imply i know is just not illegal lying to a financial institution, but when they do some sort of due diligence that may give me some troubles in the future?
