I also agree with this opinion, for the introduction of blockchain and crypto technology in the lives of ordinary people will take many years,and especially it will be hard in the third world countries where the Internet and infrastructure are very poorly developed
Well, in the third world is not so bad with the Internet as you think. Now Ilon Musk will still be giving away free internet all over the world. so technology is developing at a tremendous pace. This once again confirms that the future is almost here.
I base my words on the facts, I live in Ukraine-although it is not a third world country, but there are problems with Internet connection in a third of the country, and there are people who even hardly use a mobile phone and credit cards, so it will take a lot of time before the full globalization of blockchain technology by ordinary people
