and in other words: it's too early to know, but I think El Salvador will be a prime example of what to do in the future.
The adoption of bitcoin in El Salvador is definitely a very good step in its growth, but bitcoin is still in its infancy and in one country it will take years for the economy to develop and adopting bitcoin in El Salvador is a very good step for the future, because in the future of bitcoin and in the long term butcoin not only gives hope but can realize what they expect and will make other countries shake their heads.
When a country like El Salvador (or even an institution or an individual) decides to invest into bitcoin for the longer term, the goal does not tend to be selling (or at least it should not be) - even though a lot of additional comfort can come to any investment when it is "in profits" rather than either flat or negative.
So if anyone actually understands investment dynamics, there may well not tend to be a lot of moving around and/or trading in and out of investments that are intended to be longer term - even if some of the longer term may well have higher levels of volatility like bitcoin has had historically and it is expected that bitcoin's high level of volatility will continue in the years to come. I like to say that one of the most inevitable dynamics in bitcoin is it's likely ongoing volatility.
There are a variety of ways that long term investors can attempt to mitigate likely inevitable volatility, and one of the ways would be to get in early and keep buying and hopefully the volatility to the upside will end up causing the volatility to the downside to be less painful - or at least not force any kind of bitcoin sales when the BTC price is dropping or has dropped significantly... at the same time, if the bitcoin price is down for a long time, even long time holders/investors might feel that they are not able to sell their bitcoins... so hopefully, governments, institutions and people who are in these kinds of situations will have sufficiently and adequately established other cashflow and funding sources so that they either do not need to sell bitcoin when it is seeming to be relatively down in price and/or that they are able to continue to add to their BTC stash when the BTC prices seem to be relatively down. Buy on the dip and DCA ideas in terms of managing one's bitcoin holdings.
