The possibility is very low. Bitcoin is gonna get known by almost each and every users by the year 2022, but I don't think most of them starts using it as it have only digital form.

Probably not, not everyone has the means to access bitcoin. The ones that do might not even trust it anyways.

Its quite impossible that every one will use bitcoin or almost everyone will use bitcoin in year 2022. Of course there will be much more users than are actually using it now, but there are areas in the world where bitcoin will take ages to arrive like Africa(not talking about South Africa here), and very poor countries where not everyone has the possibility to own a computer and even less possibility to use the internet.
It is almost impossible if not impossible that almost everyone uses bitcoin in 2022.

To be honest I think not, some people are just not into these online currencies and the work that comes with it. I can understand why they say this, they already have cash why do they need Bitcoin.

Like it or not, people had to transition from shells as money to gold as money. Whenever a new better alternative comes out, there will be adoption. And if you don't like it, too bad, everyone else is.

Cash is a flawed system just so if you didn't know yet. Cash is by no means perfect.

I think there is a chance it will be used by a lot of people in that year but of course this is not sure without any doubts...

It will be used by no more than 2% of the people in the world. Not many people will hear about it then.

I thinks it's depend on price because if the price is low it's affordable and many people can get or buy their bitcoin with that price or lower.

Even if the price is higher or lower I doubt that it will not be used by everyone, no doubt majority of the people would be aware by then but its difficult to expect everyone holding and using it.
