You don't need to be save Bitcoin for a huge long period but in the next 5 years you will get almost 20 times of now what value is. Since it's inception of bitcoin from mere $0.001 to now increase millionth of times. So, don't be hurry and save your Bitcoin because the demand of digital era is widely accepted.
5 years is a really long time for many people who don't have patience to hold it longer as they will start selling their coins when they see higher price then their purchase price as their main goal is to make profits and when bitcoin will touch the price of $10k in near future I am pretty sure that most of the users will dump their coins to make profits.
