Bitcoin will not be used by everyone in 2022 since most people of third world nations dont even know how to operate a computer.Most of them even dont have a bank account.But Bitcoin will be widely used by people all over the world by 2022.
Likewise, we could not predict the future in 2022 if all people
will use bitcoin. As we notice bitcoin is increasing its demand
yearly. I dont know yet if people can easily adopt the use of
bitcoin. I guess so and hoping that every people in every country
can easily adopts the use of bitcoin. However, we could not
tell in 2022 that everyone will use bitcoin.
