I still dont see how bitcoin reduces poverty like a silver bullet (Hint: Because it is not). Bitcoin is a currency and a payment method that can only be used if you already own it or received if someone else owns it and sends to you. Same people may be lacking any fiat at hand, does not mean they will magically have bitcoin at hand. On the other hand, it does make sending the money easier, which I agree.
Of course if you are a Nigerian price trying to scam using bitcoin, then its a different question - devilishly, you will get rich from tricking people. But that does not solve a poverty problem.
Fiat will exist as long as people exist because the entire economic system is hardwired to it. Crypto is till now an alternative, maybe in future new things will come in play and the use of both will get balanced.
Yeah I kinda agree with you on the poverty thing. Like if you are truly in poverty, where you have to spend everything you have just to survive, Bitcoin ain't gonna do much for you. In fact if you are at that level of abject poverty you probably won't have access to the internet or any devices with which to use Bitcoin in the first place, or be able to spare the few dollars (cuz in poor countries a few dollars is like a few days worth of food) to get some bitcoin and move it onto the LN to use in transactions.
But at a bit higher level of poverty I could see it helping at least some. For anyone with access to the internet (and indeed plenty of fairly poor area in third world countries do have access to cell phones with probably some sort of internet capability) who can save any amount of money, Bitcoin helps because it is hard money. Even more so in countries with really weak currencies where saving money is barely useful at all since the currency loses value so much. If people in poverty are able to save a little bit of money at a time in Bitcoin, in a generation their kids might be out of poverty with the appreciation of the Bitcoin they saved. Also since Bitcoin is an open system it means people in poor places can transact with this better money.
Anyway, the idea that Bitcoin solved poverty is only somewhat true. Bitcoin is very useful for the unbanked that aren't in abject poverty, for people in countries with horribly debased currencies, for people in any country with money to invest in assets to grow their money, for unbanked areas who want to be able to use digital payments, for anyone able to save money, for people barred from accessing financial services like some countries in the middle east who don't allow women access to traditional finances or banks, and for refugees and immigrants who want to be able to bring their money with them. But yeah it doesn't help those in total abject poverty cuz those people wouldn't be able to get onto, or afford the onboarding into Bitcoin.
