If they're willing to learn cryptocurrency, and how to earn through it then their life "MIGHT" change with the help of it.
Aside from that, cryptocurrency isn't a one-stop shop for all the financial problems of those poor people out there. It isn't like a "You will invest in crypto, and your standard of living will increase" kind of thing. Of course, you need to learn how cryptocurrency works as well.

Are you concerned with those uneducated people? If they're unwilling to learn, their lives will not change. If they're not willing to learn crypto, crypto will not help them as well. Yes, we've seen investors who changed their lives already with the help of cryptocurrency, but before that, they learned as well. They educated themselves that's why they became successful. If those uneducated people aren't willing to change their mindset, they will remain poor for the rest of their lives, and crypto will not help them.

Cryptocurrency is just a tool for us to increase our standard of living. Those who are willing to spend time to learn it will be the ones that will become successful, and vice-versa.
