I would say that a cryptocurrency that resets itself is probably rather counter-productive, and in my opinion a terrible idea if you want it to go on for more than a generation. The crypto could never have any considerable value because it would all get wiped in the future, and thus investing large amounts or placing the value at greater than $1/coin would be completely useless and just be looking for a lot of lost wealth.

It is a good concept for an authoritarian government that should never expect for their currency to have any value in the international stage, but it sucks as a free market idea.
