Where to get BTC on the darknet with a bank account

[Kuram]

I've been on the dark net periodically for about 5 years and when I come across a bank account (account and routing numbers only -- nothing else), my success is not as effective as it should be. Right now I currently have a bank account that has more than $80k and want to utilize it without getting attraction from any law/government agency. Could someone tell me where I can get BTC from this bank account?
