First, it is impossible because everything that is already on the blockchain will forever be on the internet and there is no authority that can remove it, 100 years later maybe all of us in this era will no longer exist, but you know there will always be a better new generation later . if you think in the future crypto will not evolve or even die. I actually think otherwise, because digital developments will always evolve and new generations will always have a much more modern and digital mindset.
