By 2022, there will be some form of standardised cryptocurrency used by many across, now whether that is bitcoin I cannot really speculate. Bitcoin may not become the standardised currency but has sparked new faster, efficient and secure currencies.
I think however bitcoin as a currency is also, who knows what will other people say, I think that it bitcoin year will be more famous and popular than now
No doubt it will gain more popularity and attention from people by then and we will see more users getting into bitcoins but its hard to believe that it will be used by almost everyone.
