Despite the possibility that nation-states will also start HODLing Bitcoin? El Salvador might only be the beginning. I believe when nation-states start to understand that they need to hedge, and HODL Bitcoin as protection against the possbility that they might lose control of the economic/financial system, they will hedge.
El Salvador was the lucky country to officially implement bitcoins in their country and look what they've gotten so far, it's all good for them. Looks like other countries that have some doubt about bitcoins are now preferring to make a change by following what El Salvador does. If they wanted to make real change, then they need to get their hand on bitcoins in a positive way. It wasn't hard for them because they have a country to follow. It's up to those who still have doubt about the success of bitcoin if they still wanted to hold on to their negative thought about it. Do they not see how successful El Salvador right now?
