If you live in a poor country, how can you afford to buy crypto to help someone? Crypto isn't always the answer to everything. For some, spending a little on cheap coins might pay off, and they might have a big success story, but that’s not always the case.
I think it is more of the opportunity that cryptocurrency can bring and not about cryptocurrency specifically. For example, the introduction of cryptocurrency can create job opportunities for people who live in third-world countries, such as participating in campaign signatures, day trading, etc.
Like the famous saying that if you give a person a fish, then they are satisfied for a day; but if you teach them how to fish, then they can be satisfied until the rest of their lives. Teach them all the basics and foundations of crypto rather than giving them as a form of donation.
Crypto doesn't end poverty, in fact, it can make you poorer if you don't know what you're doing. if you have the right knowledge and resources, it can help you make a lot of money.
I do agree with that point you have raised.
Actually, anything can make you poorer if you make bad financial decisions with your resources and not just cryptocurrencies. In fact, investments should be made with intellectual decisions rather than hastily due to FOMO.
