I believe the direct answer to this question is no. It´s a very speculative answer however. The way we see currency will definitely change, blockchain tech is here to stay and will increasingly enter our lives. BTC as we know it will hardly replace fiat because of transations costs and sacalability. However some form of evolution of BTC or some other crypto that is easier to use might be widely adopted in the future.

Indeed, bitcoin atms are required to widespread the use of bitcoin. As far as 2012 is concerned, there is no chance of people everywhere start using bicoin for purchase/trading.  Sometimes people ignore that there are lot of countries and places where trading in cash/credit-card is preferred or preferable due to 1) no internet(lack of infra) 2.lack of awareness about crypto

Probably the possibility and capability of bitcoin to be used by almost every people in the world is always visible because bitcoin cryptocurrency is a fast growing currency which is established and operated online. Even though bitcoin is a fast growing currency, it does not imply that it will destroy the other currency which has been established decades and centuries ago. In fact, cryptocurrencies are the innovated and modern version of the natural currency like dollar and euro. Cryptos are created so that currency can have its other face that go along with the rise of the modern technology.

Yes theres a possiblity that everyone will be using bitcoin in 2022 ,its because of the technology of what we have today and as years passed our technology upgrades, therefore on that year we will see everyone even the young one is already using bitcoin.

If it's 2022 i think almost all people know about bitcoin, whether they will use it or not that i don't know. But i believe the majority will use it because bitcoin can be used as a hedge fund againts inflation and an alternative to people who don't want gold.

2022 is pushing it a bit too much.

Still in its early phase, it doesn't have enough practical exposure in the "outside" world.

I don’t know why people want bitcoins to perish away fiat forever. Fiat is not doing any harm to bitcoins in anyway. These both are simply modes of currency and their usage should be a mere choice of the user. Fiat has also served us for years. Let’s all enjoy both systems and make profits out of them.

No. Bitcoin will not fully recognizable by everyone in 2022 because there are some countries that bitcoin is still ban and illegal so if someone is holding bitcoin in that country more likely to arrested by the authories but many things will happen in 5 years this is enough time to realize they need bitcoin.
