I have started more than 15 companies in my lifetime. A few of them successful. I would do an AMA, but I'll answer three questions that you didn't dare to ask instead.
Q: What is the best advice you have for young entrepreneurs?
A: Stay away from EU. Don't incorporate there. Don't target EU customers.
Q: What is the best target market that no one sees?
A: The netizens that own cryptocurrency and can use them for payments (no ETF owning grandmas).
Q: Where do I find investors or money?
A: Don't. Bootstrap.
