The track record of crypto businesses is genuinely disgusting. No way would I ever, ever, ever, ever put money into a crypto business. Almost every single one has failed or disappeared. If a hardened crypto fan feels that way do not expect any conventional funding route to feel differently.

The few crypto businesses that do make money tend to attract heavyweight funding completely separate from banks or pipsqueak investors.

As mentioned above there's a section here to look into funding. You will get much further offering collateral. There's a lot of money swilling around. Plenty of it will be demanding.
