El Salvador becoming the first country to make Bitcoin legal tender is a major milestone for cryptocurrency. It's exciting to see the potential impact this decision could have on the country's economy and the future of digital currencies. It will be encouraging for certain countries to follow El Salvador's lead, countries with growing interest in cryptocurrency adoption around the world. Some countries, like Ukraine and Panama, have already expressed interest in legalizing or adopting cryptocurrencies. There are countries with unstable economies or high levels of financial exclusion that might see the potential benefits of using digital currencies.
The success of El Salvador likely has to do with its bitcoin focus rather than getting distracted into shitcoins.
You seem to be distracted in your own desires to frame this as a victory for some vague ass generic category of crypto/digital currencies/ shitcoins.
So in some sense you seem to consider them all to be in some kind of similar category, which likely shows that you are lacking in your own abilities to distinguish what is special about bitcoin and what is going on with the various shitcoins that are mostly either affinity scams or maybe you could consider them as test networks for bitcoin, even though there are a decent number of folks scamming and getting scammed through their various involvement in those overwhelmingly snake oil projects.
The next five years will still be an era of buying Bitcoin because I have never heard of Bukele talking about selling.
There is no need to trade or sell investments... especially something like bitcoin.
