Some of these don't really provide any real value if you'd ask me. Also, people in marginalized communities would like.to disagree with that, especially third world countries that still don't have access to the internet or even have their own mobiles and machines to send and receive crypto transactions. Sure there would be cryptos that pop almost out of nowhere in the future, but it isn't enough to be a source of income for some people who still don't have their own mobile and access to the internet.
In ten years time, so of the problems of internet would have been relieved to an extent where at least 30% of the populace of the developing countries could understand the internet usage. Anyway, to this, my concern is even education and not internet usage. Education/knowledge is a parameter to understanding cryptos and also in financial proficience to determine the kind of investment to embark on.
