As long as you waited 4 years between storing value in Bitcoin and removing it you _always_ got more value out, no matter what point in time in Bitcoin's entire history you stored it.

And not just a little bit more value..

Is an index fund a store of value? Would you recommend someone store their value there if they wanted it back out in less than 4 years? Gold? Property? Or would you suggest those stores of value are only suitable for longer time frames? How much more value does someone who stored it in Bitcoin 10 years ago have now?
