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.
Looking at your last sentence, it seems that you want to talk about trading. You are right, if someone invests in crypto or Bitcoin without knowing it, then of course it can be a cause of loss for him. Because the market is completely unpredictable. There are many people who want to invest here after hearing about Bitcoin from their neighbors. But they themselves do not know how terrible it is for them
You have answered your own question with your post. Bitcoin cannot eliminate the poverty of a nation until that country has accepted it well.
Whether country accepted Bitcoin or not Bitcoin can not and will not eliminate poverty in that country, let us not make it look like Bitcoin is a poverty alleviation kind of program, a lot of people have this mentality but as soon as they get in to Bitcoin they have become rich, perhaps there are even those struggling to meet up with their basic important needs in various countries then I wonder they can successfully invest in to Bitcoin and moreso Bitcoin is apparently for a long and not a quick and get rich scheme.
