In my country I would need about 36 months (3 years) to be 1 Bitcoin holder. And not even taking into account the price variation in those 3 years. Because I believe that in 3 years, the price will be quite higher than now.
Actually, it is very difficult to determine how long it will take to get 1 bitcoin, because we do not know how it will behave in the upcoming bull market, which may already be underway. If it happens that bitcoin is worth more than 100k or even more, then the goal of 1 bitcoin for most ordinary people bitcoin will become unattainable, since they are already burdened with mortgages to pay off their homes, or whatever, for decades.
Of course, but if we want to answer the OP quesiton, we need to start with some assumptions, otherwise, it doesn't even make sense to try to predict whatever about Bitcoin.
That's why I said that I wasn't taking into account the price variation. Many other factors could be taken into account, but we would reach a point where no prediction could be done whatsoever!
