I would consider that Bukele's approach to bitcoin is a quite a bit closer to my approach to BTC rather than Philip's approach, yet ultimately the three of us have different approaches to BTC both historically and also what we currently are doing, so it is doesn't seem very accurate to lump them all into one, as if we were all doing the same thing.
One of the main sticking point with Philip's approach is that he never really did accumulate bitcoin on an ongoing basis, even though he has been into bitcoin for 11.5 years.. so it does not even seem fair to lump him in the same group, even if he happens to be the oldest in terms of length of time that he has had as opportunities to accumulate bitcoin. He also sold recently and is cheerleading for lower prices in order to attempt to get a better BTC buy price while at the same time putting quite a bit of faith in the dollar.. and getting dollar yield.. which seems to be somewhat in tension with a motivated bitcoin accumulating approach.
Bukele does seem like a somewhat newbie to bitcoin, yet if we are talking about his countries accumulation of bitcoin (in comparison to his own personal bitcoin accumulation - which we do not really seem to have information about that), his country really has ONLY been announcing themselves to have been publicly accumulating bitcoin since sometime around the time of their June 2021 announcement that they would be getting into bitcoin and establishing bitcoin as legal tender in their country. They made several BTC purchases between June 2021 and recently; however, they did seem to slow down in their BTC purchases since about May 2022, and ONLY announced one time purchasing some BTC at around $19.5k.. perhaps at around the same time that Philip was selling BTC at around that same price. So El Salvador and Bukele proclaims to have had never sold any BTC from the ones that they were accumulating, though it is not really clear how they are funding some of their BTC related projects, yet apparently that is coming from other funds - not their BTC treasury accumulation funds.
There still can be some overlap with similarities, yet with me, I proclaim DCA to be a strategy that is good for beginners and good for anyone to get into while they are still trying to reach some comfortably high levels of allocation towards BTC, and I proclaim to have had largely met my BTC accumulation goals in late 2014 - even though I did continue to feel compelled to accumulate in 2015 and 2016 - and maybe on a personal level I have been feeling as if I am somewhat back into BTC accumulation since May or June 2022, but my BTC accumulation is likely more in line with buying on dips rather than being very close to DCA - especially since I am also adding some new funds into my BTC purchases rather than just using money that I had accumulated from selling as the BTC price went up.. and largely that money of selling as the BTC price went up ran out around $18k-ish.
I promote DCA as one of the best of newbie BTC accumulation strategies - but as someone reaches more and more BTC accumulation, then his/her options should become greater because his/her BTC stash has increased - and so El Salvador seems to still be working its way up to getting towards higher levels of BTC accumulation, and I assert that I had already largely gotten to adequate and over-accumulation beyond my targets after late 2014. Philip seems to have had never gotten there, even though he sometimes talks a BIG game - and he even gives what seems to be opposite advice in regards to proper mindset when he refers to the 50 year old with 100 or more BTC as if that person should be in a desperate state to sell BTC, when the opposite seems to be true.. because in fact the 50 year old with 100 or more BTC seems to be having way more options because he has BTC versus someone who does not have much if any BTC and is just sitting on his hands and buying $50 of BTC a week, which seems to be something close to what Philip is doing - which does not seem to be the place that any 65 year old should be in who had been into bitcoin for 11.5 years and seems to be dabbling with baby level BTC buys and praying for sub $10k BTC prices that may well NOT end up happening.
So BTC accumulation party depends upon where you are at, and if you put yourself into a place where you do not have coins, I would suggest that your BTC accumulation should be way more assertive.. rather than waiting around for the BTC price to drop.. and I suppose, even if El Salvador got nervous because of BTC price drops since May 2022 (or they might have been forced by public pressure to be nervous and to lay off of their aggressive BTC buys), they are showing signs of getting back into a reasonable BTC accumulation level that would fit for someone that is in their somewhat early BTC accumulation stages including that their BTC is not in profits and continuing to buy BTC will bring down their current average price per BTC.
