If you actually are a US resident and declare that, you would be breaking the law.

And if you receive payment in a US bank account and declare yourself a non-resident, expect questions to be asked.

Payment is in bitcoin.

It's much more difficult to track. You can convert your bitcoin to cold hard cash at an ATM anonymously.

Fact it's paid in Bitcoin is irrelevant both to being taxable or being tracked down if need be.
