Germany did it and maybe there is a picture of what happened to bitcoin, then it just formed a little bubble that would cause panic in the market in the short term and after that bitcoin found its recovery point again.
Germany never wanted its bitcoin anyway, so it was going to sell eventually. But El Salvador wants to keep this for the long term, so I doubt they would sell off large parts of their reserves at once.
Even if they do that, who doesn't want an opportunity to buy the dip? (Besides chronic bitcoin haters, that is. But normies would relish the chance to buy sub-70K bitcoin again).
And we saw that there's nothing much big impact created with the dump they have done so there's huge chance that if El Salvador did the same if they really want to take their profits well people will just do the same approach just like what those dumping/profit taking event came. There's actually nothing spectacular about that and people nowadays especially those oldies in the scene is waiting for that opportunity to catch those dips.
So people should be calm and stop their worries about those they think negative possibilities since Bitcoin support is more stronger than those negative actions done by those certain institutions.
