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

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

I see some merchants doing 1,000–three,000+ trades within the last 30 days, which is crazy volume. I needed to ask individuals with actual experience:

How do you safely obtain funds from so many various consumers each day?

What sort of financial institution accounts do most retailers use — personal, current, coperate, or a number of accounts?

Is it advisable to maintain separate accounts just for P2P activity?

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

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

Any errors newcomers make when starting merchant-level volume?

I’m making an attempt to study the right and most secure solution to construction issues before scaling up. Would respect recommendation from skilled P2P merchants.
