Everyone always wants to buy bitcoin in the past, but for some reason, people don't want to buy bitcoin today at $55k/btc
I know about this... I started buying bitcoin in mid-2013 at $100/btc, but I would have preferred to buy bitcoin at the price of the previous year, $10-12/btc same as the Winklevoss twins
I remember thinking in 2012 when it was $100, that if I used my $1000 to buy 10 bitcoins, instead of the silver I was stacking, that I would have a considerable percentage of all there will ever be. Knowing the world population was in the billions, and with my 10 BTC, only 2.1 million people could have this much, I thought that would be cool. But alas, I did nothing. If only I did some research back then...
I think the most sensible approach now to value bitcoin is looking at the market caps of everything else, and then figuring out how much of that market cap is inflated by fiat. Housing for example is simply inflation and money printing, as are equities. So when we realize that the market caps of things can be easily 100 Trillion, and likely more, and this is based on a broken money, then it makes very logical sense to conclude that Bitcoin could be 100 Trillion.
Doing the next 100x increase though will be much harder than the previous 100x for bitcoin, and I'm sure there will be lots of selling at $100k and $500k. But I also think once we get into these values, it can move faster because things will be very clearly broken. Its just like a ship taking on water. It begins to list, and maybe many people don't notice, but at some point where the balance changes, it has a very fast change in orientation before finally going down. (ie. Titanic coming out of the water just before the final plunge)
