let me put it this way for you:
what are you looking for in bitcoin?
more profit on your fiat? or using a decentralized currency and reach financial freedom?
what you asked is the first one "more profit on your fiat" to that i say, you have to suck it up. those people in 2008 and early days that got bitcoin for free are early adopters who believe in bitcoin's future and you didn't.
if it is the second one (although your comments say otherwise) then your main question becomes meaningless! if you want to benefit from using bitcoin then its price wouldn't matter at all.
I am a holder for pension or early retirment from (fiat/crypto) work in 10-20 years time - for me and my brother.
then you are a long term investor looking for the profit.
in that case as i said you (and other new people like you. me included) we have to suck it up. we obviously have lost a big chunk of the rise so far but it is nowhere near the end of the rise.
the same way we are now looking at $1000 (9 months ago) price with regret, others will do the same at the current price of nearly $4000 with regret in 9 months in the future.
you say that the rise in value will continue (as collective convincing OTHER people to buy bitcoin at higher price), and it might not be so. What will people gain from buying a 100K$ worth one bitcoin? What would be the logic of that?
