Bitcoin is not a magic wand which will end world poverty. It simply doesn't have the power to end such a massive thing. Also bitcoin is not a payment system anymore. We have moved to a different goal long back, when the confirmation time increased and transaction fees hiked. These confirmation time and transaction fees is going to be increased again and again. So we will move from the initial goal further.
Bitcoin has now purely became an investment asset. IT can provide a huge return which any other conventional investment will never be able to offer ever. So I take bitcoin purely as an investment and a trading asset. I earn profit and keep it for the future.
Transaction fees pretty much ruined what Bitcoin is and also the confirmation time which it should be fast and cheap transactions. Could it revert as to what it was?
Aside from those, if poor people you are saying, really poor people then I don't think it will help them especially those who are not technologically literate and some who have no literacy. Also considering the financial standing, if they can affor to buy a android phone, computer, or anything used to connect to the internet and browse then they can join in but if not then unfortunately they can't. And the internet fee or they can just go and connect to free wifi spots.
Let's face the reality. Bitcoin has its requirements set and you need to have those in order you can access it and profit from it.
