I had big banks shut my accounts down when they caught wind of dealing in farming hemp but a local credit union welcomed the business, embraced the fact that hemp is legal under the farm bill and extended a loan for the farming side of the operations. Maybe check out the small local branches as well as the international.
I have some friends that are selling CBD online and they don’t seem to be running into any issues… yet (knock on wood).
I have used cryptocurrency and still do for some transactions but the prices of some cryptocurrency are so volatile you can lose 5-7% in a transaction. But it is super fast, borderless and operates 24/7 (no holidays/weekends). If you go this route, look into stable coins like USDC and Dai.
All the best in your ventures!
