And particularly, I'd like to do it all for money. Is there any project you can think of I can participate in?
That's a very sad thing. Like you don't know jack shit about how cryptos work or even understand the source code for that matter and you expect to get paid? Isn't it ironic how a person who knows a lot more about cryptography created a system for free and you a person who doesn't know anything wants to get paid? Well, things don't work the same way here. Bring skills to the table to get paid.
Wow man, you're horrible. He's not being rude, he's just asking if he can leverage his cryptography knowledge for a job or to earn some money. Rather than treating him like an asshole for daring to say that he wants to try to use his time and skills to make some money, how about give him some constructive feedback or tell him how to improve - although I'd assume you have no real feedback to give, hence you instead just reverted to attacking him so you could still get a post in.
Ridiculous. Just because open-source software exists doesn't mean anyone who works on stuff for profit is a money-hungry "sad" person.
To the OP: There are many startups hiring people with knowledge of blockchain technology specifically. I'd try to leverage your cryptography knowledge to learn more about how a blockchain can be used in different contexts and industries.
