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.
Bitcoin will not be used by almost everyone because if bitcoin will be used by almost any people around the world then bitcoin will lack of its supply and have a shortage and that is why bitcoin is not designed for everyone. I think bitcoin will just be accepted by the shop owners and not everyone because that is very impossible.
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.
We may say that there will be enough bitcoin for the whole population of Earth, but you need to consider how many are interested and not interested in these digital currency. Not all people will use bitcoin, they can't even surf the internet,especially the country with internet restrictions. With it's popularity nowadays, we can't deny that it will be more popular than today, but still, there are always haters.
Let us not thing too deep with this one. Right now, not even 10% of the population is using Bitcoin yet the value of Bitcoin right now is 1600$ which is higher than any fiat currency in the world, now imagine if almost everyone is using Bitcoin, then the price of it will adjust accordingly its not that Bitcoin is a limited supply it won't be enough for the whole population of the Earth, like what he said earlier the price of Bitcoin will surely adjust according to the demand it will get from us. That is how demand and supply simply works.
Thinking about what you said, there are just a couple of people that have invested in major companies yet each share/stake costs much more than bitcoins. How's that for "what if more people" invested? I think it still depends on how much investment is present. It's possible that a billion dollars of a market cap of bitcoin is just from a single person. 1B market cap is such a huge deal up to now.
There can be many people using bitcoins but the price wouldn't pump up because the people using it aren't investing anything. There are days when the price of bitcoin barely moves but the number of people using it surely is increasing. That alone proves that not everytime goes in in the bitcoin world, there will be an increase in price.
