I think they have done it before they've investment on bitcoin since late last year.
And now I would say that it's hard to see wherein they are right or wrong with their investment before the price seems to be going down hard again that they might be losing money in their investment just saying.
Anyhow, I would say that El Salvador might be a good use case on how good bitcoin could really be a hedge specially long term (we can't judge them for holding just for a short amount of time, maybe we will see a clearer picture in the next halving, and bull run).
