It is often said that Bitcoin is a hedge against uncertainty. And that's it.
As compare to gold? Bitcoin hasn't been tested as a good hedge against uncertainty though.
Uncertainty could have several connotations to it, Bitcoin could be seen as an alternative to the uncertainty in supply of cash, credit crisis and other fiscal policies the banking sectors implement which affects the nation's economy. Bitcoin has the qualities of immutability, decentralized and a fixed supply which makes it a good hedge against centralization.
So you want to buy BTC and HODL until 2050?This sounds crazy.

That really is not that crazy. There are people who are investing in Bitcoin which would be accessed by their kids in 10-20 years, 2050 from then is not far off.
