If you're doing k/day consistently, you're past the point where regular consumer bank accounts will work. They're designed for personal use and flag any business-like activity.
What you actually need:
1. Business bank account - Open an LLC/Ltd and get a proper business account. Mercury, Relay, or even a local credit union that works with e-commerce.
2. EMI/PSP as backup - Payoneer, Wise Business, or similar. They're more tolerant of high volume e-commerce.
3. Multiple receiving accounts - Don't route all k/day through one account. Split it across 2-3 business accounts.
The 20+ accounts approach is a red flag factory - banks share info and you'll end up on Chexsystems/EWS making it even harder to open legit accounts.
What country are you in? That affects which options actually work.
