How do high-volume P2P merchants safely receive funds while selling crypto?

I’m planning to start out doing bigger quantity on Binance P2P and ultimately develop into a merchant, so I’ve been making an attempt to know how skilled sellers handle every little thing safely.

I see some retailers doing 1,000–three,000+ trades in the final 30 days, which is crazy quantity. I needed to ask individuals with real expertise:

How do you safely receive funds from so many various consumers daily?

What sort of financial institution accounts do most merchants use — private, present, coperate, or a number of accounts?

Is it really helpful to maintain separate accounts only for P2P activity?

Are there certain banks, wallets, or cost methods that work higher for high-volume trading?

How do merchants scale back risks like frozen accounts, chargebacks, or suspicious transaction flags?

Any mistakes newcomers make when starting merchant-level volume?

I’m making an attempt to study the right and most secure method to structure things earlier than scaling up. Would respect recommendation from skilled P2P merchants.
