You have a valid point, it doesnt need intrinsic value...but thats not how people think.
A lot of cultures still store money under mattresses or buy gold because they believe in intrinsic value.
They also do this because they have core believes of "I understand what I own".
And they also believe that when things go wrong, there is a process and an institution that backs it (like the police and lawyers).
Considering that it took people a few hundred years to believe that the earth is round,
your saying that millions of uneducated people are going to rush all their hard working money
into something that they have no clue how it works, and have only heard that its been hacked so many times without policing or retribution.
All these people are so progressive that they will change their minds within the next 5 years and accept a currency that
is not backed by financial institutions....A "currency" that is owned by 0.00000001%
And these people who own it dont want to give it up because "holding on" means greater returns.
So where are these people going to get their share of it as its limited (hence the current bubble)?
Further then if it becomes somewhat accepted that no government will step in to regulate it,
as they are just "happy" with the fact that the only power they have over people, they are ready to give this up...
Nobody else has pointed out either that there are over 750 crypto currencies and only maybe 5 that have panned out.
That's not to mention, to make your own cryptocurrency is pretty easy as well as you just copy/paste the code.
(Just like myspace was popular in early 2000s and now its ...gone)
So for any cryptocurrency to become great, it first needs to be commonly accepted, then we need to figure out
how government is going to approach it, and then we need a track record of at least 20 years to become
integrated into the system.
Nobody really sees there are some major concerns with this...
If it becomes something then I dont need to be the first person in, hard lesson I've learned from the stock markets.
