We should also keep in mind that El Salvador didn't lose anything. 1BTC is still 1BTC. I know the problem may be another, but still, I think it's too soon to tell that the Bitcoin bet was a fail. There is still much to work on and a lot to evolve, embrace, etc. The more we see fiat going down, jus tlike what is happening in the Netherlands and in China, I think it will call for the people's attention regarding alternatives. People are desperated and usually humans adapt. I still hope the best is yet to come but also that the worse is also yet to come!
And as we have seen, El Salvador is still buying just like that they disclosed they bought btc at 19k level. So who knows, even at 20k level they are slowly stashing some? It is indeed true that they are not losing in this market if they are not yet selling. As they are very positive about btc market, they won't sell at a loss. And remember, this is not the end of the road for btc, so yes, there's hope that in the next coming months, btc will recover and may reach higher price levels.
