But the internet technology is spreading at a viral speed, and now even in a third world country even a poor person also can have access to the internet and it is not far away that everyone will have access to it.

nothing is impossible, it can happen.
but I guess it did not, although the technology is growing, I think they are very many people who very rarely even touching his computer. everyone will be using bitcoin in 2020 if bitcoin already made in the form of offline

It will reach to all over the world by then, but the fact is how many of them will start adapting it, if adaption level is high, then we can expect much higher price of bitcoin in future.

bitcoin age is 7 years old now. and in 2022 there will be six years old again. certainly picture that year. 2x the same as a result of the development of the current bitcoin.
maybe the price will be heading to over $ 800. and the user of a 2-fold from now. hopefully it happens. bitcoin continues to grow

Yes there is really a high chance that people on that year will use bitcoin and so far bitcoin is getting accepted in huge market in US and that is a step to increase the users of bitcoin.

Actually even in third world countries, bitcoin is already been used, it's just that its price is high so by now the only easy way to have one is to earn it...But since jobs are not easy in third world countries, it will be favorable to bitcoin, people might know it as an opportunity..Many would adopt but I still don't think that everyone will be working for bitcoin for a long time..

Bitcoin will really be the most popular payment method in the year 2022 and bitcoin will be used by most user if there will be shop that have accepted bitcoin.

No I do not see this happen because the fact is that there are still other currency's in that year that are still a lot bigger.
I think this will even never happen because the banks are really against it and they are most likely gonna make a coin for themselves, so they have the power over it...

I don't think bitcoin can cover whole world markets till 2022.because the price of bit coin is too much high and in this case they can't even cover world market till 3022.

Bitcoin will come likely do not destroy the banks it may become mainstream but not that kind of mainstream.
