Binance unverified account restrictions

Binance to continue add new restrictions for unverified accounts. I have 10 unverified accounts on binance because I have 10 trading bots with different strategy and I need to have 1200 requests per minute for each strategy.

Could you help me to find solution? Can I verify this accounts with same passport ID, or binance has restrictions for multiple accounts?

I've tried to ask binance about using Sub-Account Feature, but I've no any response maybe because this feature for corporate users only, and I'm not sure will I have different API keys with 1200 requests per minute for each for sub accounts or not.

I would be grateful for any help.
