Like yourself I am very positive about bitcoin moving forward, especially with all the issue going on in the world and during this crazy time in our lives. Now I can't agree that it's a "guarantee", as guaranteeing anything is a fools game.  There are certainly never any guarantees in the financial world, especially for a digital currency. 

"It is often said that Bitcoin is a hedge against uncertainty. And that's it".  I am not sure what you mean about this exactly.  Do you mean bitcoin is used as a hedge in a good way or people say it's the only positive factor of bitcoin?
