As an option to purchase crypto currency right now, while prices have fallen very much and wait 5 years. There is a big chance to multiply your savings.
Well this is holding. You must hold but not for so long time. Although there would be chances for you to multiply your profit ratio if you buy bitcoin in this era and then wait for such long drastic time. If you have got extra money too, which can be used in other sources and earning can be made with better living then it might be okay. But in restricted sources, dont ever go for such long waiting.
