Have they already sold out their coin which that can determine their loss?

It might have a loss maybe millions of dollars supposedly but I think that didn't occur just because they still holding their Bitcoin and didn't yet sell to exchange.  El Salvador has received a lot of criticism now but I think they have a wise decision of having a strong fate on Bitcoin, they never sell what they have bought last year, in the end when Bitcoin will bounce back, they will laugh at those who criticized.

Even though Dania Gonzalez, Deputy of the Republic of El Salvador reveal and said, "Now, it is time to buy more".
