There's probably another way of looking at the situation if asked "if it's too late to buy Bitcoin". It's an accepted FACT that Bitcoin has not reached it's true potential. It's an accepted FACT that Bitcoin has not absorbed all potential participants in its market. My personal belief is that Bitcoin will never stop breaking its own all time hign of it still has not broken Gold's market value.
Impossible? I believe not. Improbable? Maybe. BUT nation-states have only started to notice. Large asset managers like BlockRock have also only started to notice. Shower thought.
You are correct bitcoin still have more potential to absorb. This word ''too late'' is really an enemy of progress even in our daily life because it bring so much fear to start afresh or try new thing as well as bringing limitation to our progress. so many people even me have lost so many opportunity thinking is too late to start afresh or try new thing at the end it turn out to be an opportunity lost. This is also the reason why so many people who could that have large bitcoin portfolio today to miss the opportunity because they though is too late to invest. So many people now are regretting looking at some years past when they had the opportunity to invest in bitcoin looking at the price of bitcoin now.
