I am not sure that this is going to happen even almost everyone in the world are allot of people. Bitcoin is becoming more popular but I do not believe that it will be as popular like websites like Youtube or Facebook.

30-40% of the world population by 2022 would be an unbelievable success. Even 3-4% would be more than 200 million people and would be a huge success!

I think we should stay realistic. Bitcoin will not entirely replace the current system in a few years. That needs a lot more time, because there are a lot of structures and dependencies tied to the fiat system. Habits do not change that fast. So most realistically Bitcoin will coexist with the old system for decades, slowly gaining market share.

Of course it's possible that the move to Bitcoin will be faster in some sectors where the advantages are more relevant (e-commerce) than in others (paying farmers).

ya.ya.yo!

There aren't very many even-tempered posts on this topic, but congratulations on having one of them. Everyone gets caught up in the to the moon mentality and loses touch with reality, and that is that change happens slowly, and drastic change happens even more slowly. Bitcoin will likely never replace the current monetary system.

currently the development of increasingly widespread bitcoin, and it should already be used almost everyone in 2022.

No such trend does not continue and it is not a linear trend so do not hope like this for that time.

I dont really cant tell if will people will use bitcoin in 2020, we cant say anything safely about that as there are so many factors involve in that coin. But i think it will have many competitors by that time and many ALT coin dev will make more move to get bitcoin died.

I agree with your idea that if everyone started to prefer bitcoin then banks will be imposed to adopt bitcoin and then bitcoin will get a strongest support and the governments will also allow bitcoin as without bitcoin their business will numb.

Not everyone but for sure more people will be using it, its getting recognize as even altcoin now having its own proposition value

If we at some point in the future manage to get around 5 to 10 percent of the world population to use Bitcoin then it can be seen as a mega milestone. Getting everyone to use Bitcoin is indeed impossible.

I think that in 2022 nothing will change, and % of people who of bitcoin useres will not increase majorly. So better to think how to make big money with bitcoin.
