5 years would be a very long time. For me, investments in bitcoin is more for a short term investments. By short I mean, months or within a year. Within that 5 years in time, a lot can happen to bitcoin. Investing in bitcoin now, is the perfect time specially that its price today is way lower than its previous price where it almost reached 20k dollars a piece. You don't actually have to wait for 5 years because after a few months time, you can already see how much the value of your investments grow after a few months and before the year ends.
