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.
so do you think all the developed nations are well equipped and everyone knows how to operate computers and do you really think that everyone has a bank account ,if so that is just silly ,people mainly use bitcoin to trade and to gamble and the people who are not interested in doing so would never bother about bitcoin.
I think it is really big chance mostly people in the world will use bitcoin. people wants buying or selling practically. bitcoin is very very apropriated for buy or sell some thing in internet. so people do not need buy with credit card they just only newd their smartphone, by scanning code or send via address. it is normal for people to looking some profit, it is proof that bitcoin is awesome thing.
