How is that related to the topic at hand?
and asset backed crypto? not crypto only, whold economy.

Nope. Bitcoin will remain as long as people use it. Even one person using it means that it is still alive. Again why would people trust a asset-backed crypto which is centralized by the government for supply? It is not different from fiat currency and thus will suffer the similar problems of deflation, continuous printing.
While the situation at Venezuela is commendable, one should remember that not every country is in the same situation so it not something that will happen.
