If you are in the USA, the Regulation CrowdFunding (RegCF) exemption from the SEC would allow you to raise a million dollars, but the compliance costs (beforehand) would be 100k. There's also Reg A+, Regulation A plus, that allows you to raise tens of millions from accredited investors, and compliance for that runs into almost a full million dollars.

Then, there are legal fees, and sundry expenses. It might well run into several million dollars when you add the marketing costs, and the costs of running an almost year long road show at various Crypto events around the world.

To sum up, it's something that wouldn't agree well with the faint of heart.
