the 2 big qustions that keep coming up are
is bitcoin a bubble
is bitcoin an S-curve

the answer
its actually both...

depending on what your looking at.

if your only looking at the HIGH price of a given time. its a bubble.. the speculative hype and air which can inflate prices aswell as burst prices,
.. like a bubble.

but if you chart the price data and draw a line along the LOWEST prices long term you will see the true value. the part that no one is
stupid to sell below.

think of the long term lowest line as a water line in a bath.. its a point of resistance.. anything above that is speculative hot air that fluctuates (grows and pops)

we are still in the first decade of a many decade life of the coin. which based on things like coin supply (block halving events) and population saturation will  have the waterline in a S curve.. and then variable amounts ontop for the speculative bubble based on the small amount of coin moving on exchanges that ends up causing more volatile movements

anyway here is an image for the younger generation that can only understand images
