Yes.. countries.. just like individuals.. can get distracted into shitcoins or thinking that they are going to be able to do better with some kind of a non-sense strategy that might be more "crypto-friendly" or hospital to a variety of coins (in order to diversify.. blah blah blah nonsense).  Those countries will likely punished if they are not able to sufficiently focus on bitcoin.. and bitcoin-related matters and to keep their eye on the prize.

So there could be some kind of a learning curve in terms of actually not allowing shitcoins or shit projects to distract you, but also to learn the various ways to employ strong-hand actions rather than caving into various pressures to NOT manage your bitcoins with sufficient and appropriate care.

There are a lot of countries that are way BIGGER than El Salvador that could potentially over-take El Salvador's first mover advantage, because they have incomes that are way higher than the income of El Salvador.. and a country like Mexico could over-take El Salvador - so long as they might be able to make sure that they are mostly focused on bitcoin rather than shitcoins.. and there are a lot of countries that are way BIGGER than El Salvador, including that they have way more natural resources too.. and some of them might be so tied into various dollar (or fiat - including having their own currencies) systems that they are not really ready to recognize and appreciate what bitcoin has to offer them, so in that sense, El Salvador will likely prosper way more relative to those fiat-focused countries.. which will likely include ongoing transfer of wealth from the no coiners and low coiners to to the bitcoiner.. whether those bitcoiners are individuals, institutions or countries.
