it is a bubble. but what you got to realise is that the housing bubble also had technology and infrastructure, businesses built on top of it.
a bubble is not about vapourware that vanishes into zero value once people realise its valueless.. a bubble is about something real that expands above its natural level based on alot of hot air(speculation).
this means that there is a natural level of value.. and the speculation ontop is the empty expanse that can burst.
with all speculation on assets there will always be a expansion of the price based on pure idiotic speculation/value over pricing.
and when it bursts it doesnt go to zero it just drops to a natural more realistic value, these natural realistic values are found on the markets by 'resistant points', values at which people will refuse to sell at because they deem the asset holds more value. some people call it 'the new low' or 'the new bottom' and yes the housing market did not drop to zero where people could buy a house for 1cent, but it definitely had a bubble and that bubble did burst.
so atleast realise that bitcoin is in a bubble. and know the real issue is that without good real utility. the natural waterline at the bottom of the bubble can decrease. which is why people should care more about the infrastructure, business and utility of bitcoin because without any of that holding the water line up, then when bubbles burst it causes more devastation to the fiat lovers who see the price crash more
I too think it's a big ass bubble that is going to pop soon. What do you think the real value of 1 Bitcoin is though? I would say $1000 or slightly more of whatever it costs to mine 1 coin in electricity bills. I don't mine so I am not up to speed on that one. And in my opinion Bitcoin has zero utility as of now. The real utility is in the Blockchain technology and it has a price tag of $0 because it's essentially free. Bitcoin can come and go at any time but the Blockchain tech is here to stay.
