its not really about FOMO demand
there always have been many people for months now willing to pay well over $100k/btc
these are people such as those in the pacific islands who's mining costs are $400k and so any coin at market rate way below $400k is seen as discount
the reason why the price hung down below$100k recent months is not lack of demand. but instead "WHALE WALLS"* creating a resistant barrier of large market orders whereby the price could not pass such limits.

*walls: super large orders created, cancelled and created, never to be filled but instead to cause a resistance limit of price movement
simply having the whales remove their walls allowed the price to move freely up
..
the question you may now be asking is why would whales put in such wall size orders to prevent the free movement of trade prices.. the answer is the whales wanting to short the futures market and also buy cheap in a controlled price..
so to short the futures market they want to resist the public free market from freely rising and hurting them on their futures marketnow they have their fill, they are willing to let the free market open up a bit and rise..when they have their desired goal, they are then willing to let the free market open up a bit and rise
...
the question you may now be asking is, how do you recognise when these whales are doing this tactic, well:
when you see a stepping stone effect on the market history of stability then temp volatility, and then stability again

controlled price within limits using wallswalls removed walls set at new level
you can also look on many markets at their current orderbook of active orders to see the large wedge of orders sat at a certain distance from the spread. where you see the numbers cancel and re apply multiples times without getting filled.
this cancelling and re applying is so that if any minnows or sharks put their orders at those prices the whale drops out and reapplies order to go to the back of the list at a certain price so that the sharks and minnows get eaten first at a certain price point to ensure the whales orders are not filled first if the market was to jump by a competing whale wanting to raise the price
