If not everyone used bitcoins in 2022 probably it will increase the number using bitcoins in 2022.
I doubt that everyone will be using bitcoin on year 2022. The awareness will spread throughout the world but thinking that all of us will be using it at the same time is not going to happen. 5 years from now, is not enough to make everyone use bitcoin by that year.Don't think that the supply will lack for all the potential users of bitcoin. Because if we are going to become many, the demand will be higher and that's the start of bitcoin's price to increase. Just like what is happening now, even there is a limitation for the supply still many are going to get into it because there is so called mBTC or satoshi's.
Widespread bitcoin usage will definitely cause some issues with the scale of the units. there aren't enough bitcoins in the world for 7billion people to use. I think when bitcoin gets to that stage, there will be a requirement for something that is even smaller than mBTC.
There is enough bitcoins for the 7 billion people in the world. And the price will only adjust because of the demand and it is going to make the price higher and if you did understand what I said, that is going to make every satoshi counts. By that time, 1 satoshi will be not just 1 satoshi anymore for us because that will have a higher value.

You don't know me. You don't know any of us so never question someone if he can "afford to think that deep and far" because you simply never know.
) Something that's happening on a small scale doesn't go up on a bigger scale, at least not right away. There might be some success on a small scale but that doesn't mean that large companies would take those into account. They would just start thinking about it when the market is finally booming and then just buy the whole thing. Basically just taking what's profitable away from the small scale businesses.
