Even though I disagree with the approach, if I was going to give a strict answer to your question, I would say get out there and find and engage investors that are NOT involved in the Cryptocurrency space. You could also source money from your friends and family. Basically, just search for what startups do when they're trying to raise money, make a list of all the strategies, and then see which ones work for you.
Good luck!
You know what it's like. People not in the crypto world think you're some kind of crazy hacker when you mention bitcoins et al. I appreciate your time.
Thank you.
