Bitcoin was created in 2009. There are not enough data points to make a reliable prediction that it will go up again. This time a lot more people have had time to think if bitcoin and crypto are going to work at all. Also, there might not be enough new people after this cycle to join in the frenzy and bring the price back up. We might very well be at the end of the pyramid.
If this is the end of the pyramid scheme, then thank goodness.
There is some legit usage for blockchain technology. Like Internet based distributed & encrypted storage (erasure coding FTW). Beyond that, I don't know.
