Most banks are risk-averse and will not entertain proposals related to cryptocurrency or if it remotely endangers their compliance position. Bankers tend to be anti-crypto so you can expect to continue to encounter difficulties with traditional banks in the foreseeable future.

Accounts will depend on which country your business is registered in and which business model you operate. Banks will look into that for compliance purposes.

If you want flexibility, sign up for Estonia's E-Residency. Then register your company in Estonia. When that's done, you can quickly and painlessly open an account with Holvi. Holvi can open a business account for you. I'm sure they are crypto friendly.
