Advice about binance P2P and banks

Hello, I am doing p2p in some centralized platforms (Binance), I lately began to maneuver high volumes similar to 60Okay USD every 2-Three 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 "You want to create a business account and begin justify the transactions of promoting/shopping for crypto by creating invoices for providers", my question is, will this no carry a authorized difficulty? I imply i do know just isn't illegal lying to a bank, but if they do some type of due diligence that may give me some troubles in the future?
