We need to know that crypto doesn't perform any magic. If the country is poor, the government should help its citizens upgrade to a certain level where they can help themselves.
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.
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 will answer this question by pointing to this forum or other forums related to crypto currencies that has several activities that pays in crypto (Bitcoin/USDT), like signature campaigns, bounty campaigns and some contests as well. It is not a must one will have to buy Bitcoin or Sats, because one has found him/herself in some poor country, but how to make use of the internet countless possibilities and take advantage of it.
Bitcoin/crypto industries came in as a rescue to lots of people in some of these poor countries, where I stand is, if the country leaders don't have what it takes to take care of its citizens, and the citizens finds peace in the use of crypto related activities to meet up with life's needs/demands, they should not fight against it if they can't implement its usage within the territorial regions of their leadership.
There are reasons why DYOR needs to have its own play in the crypto community when it comes to investment, to avoid losing your hard earned funds to a project that will not survive the test of time.
When you say...
Crypto isn't always the answer to everything
I agree with it, if you will also agree that money is not the answer to everything.
