Advice about binance P2P and banks

Hello, I'm doing p2p in some centralized platforms (Binance), I just lately started to maneuver excessive volumes similar to 60Okay USD every 2-3 days. The began to ask where the cash is coming from, I've no replied since banks in my nation aren't crypto pleasant, some suppliers of crypto that I have, (additionally they do p2p) began telling me "It's essential to create a business account and begin justify the transactions of selling/buying crypto by creating invoices for providers", my query is, will this no carry a legal difficulty? I imply i know shouldn't be unlawful mendacity to a bank, but when they do some sort of due diligence that may give me some troubles in the future?
