It's completely unclear. I can't tell you the year in which bitcoin will begin to be adopted by the masses, but I can tell you that it's definitely going to happen. There's nothing any government can do about it to be honest. One day, whenever that day may be, bitcoin is going to cause a revolution.
If the governments around the world start implementing strict rules and regulations then we would see a shit in momentum by the majority as they start investing in bitcoin scrapping the old age systems and so the almost comes into action since i am sure the shit of everyone going digital even 100 years from now is just a dream in my opinion.
Yeah, even thinking that majority of the population will go digital in 5 years is a bit hard to fathom. People are dedinitely going digital but when in comes to the monetary system, it would be hard to realize. Right now, especially with the rate bitcoin is moving up, of course morr people will be interested in using it but for normal regular people so are so used transacting with physical money exchaging for products, i think it would take a long time and something to happen drastically for them to move to using crypto.
