2022 Is way too early, let's say about 2030, by then things will have changed a lot. People will be using it everywhere because they are going to be looking for a way to move money outside of the government radar and bitcoin will be the only gateway for freedom.
2022 is the way too early but the speed of bitcoin to success is also very faster and have crossed a longer way in a few years and is going to be a global currency in a shorter time so you will see 2022 that bitcoin will be everywhere and with everyone around you.
I agree with that. The 2022 is just 6 years from now. Not even 5% of the world population will use bitcoin then.
