Bitcoin is too unstable to be used as reserve asset
And yet there are people, companies and even countries, like in the case of Venezuela, that are doing exactly that, the truth is that no one really knows what it is going to happen, it is obvious we trust that bitcoin is going to be fine and do great during the next decades but that is still a belief and not a fact, so it is possible that all of those that are using bitcoin as a reserve asset are being foolish but it is also possible they are the ones that are correct and everyone else is wrong, after all it will not be the first time a minority of people were correct while the majority was completely wrong about a subject in particular.
