the ballast of a currency is given by the social cohesion of a society.
Bitcoin has no such characteristics, so it has no future.
You can bet against it, you just can't assess the time horizon of your downfall.
This is first time I hear the currency ballast. I don’t travel through times and I can’t tell what the future holds for cryptocurrency, but I do know that as long as the crypto community keeps growing strong Bitcoin will not die, we can definitely say they serve that purpose. The only time Bitcoin will end for good is when the community ends, because when there is nobody making use of it, it will become useless and stop functioning. Cryptocurrency is quite different from every other type of money there is.
And if it happens to end like you have said (which I know is not going to happen) there’s still nothing we can do about it than for everyone to just give up. We all understand that Bitcoin is a risky investment, so everyone should be ready for whatever that follows, and it’s one of the reasons you’re told to only save what you can afford to lose.
