Blockchain as a technology is revolutionary and will be used in niche problems outside of crypto.
One thing that most people seem to miss is that money is only as good as our faith in it. No matter what instrument you use this has to apply.
Reason, too much money has been invested into them. I believe it’ll trickle to zero slowly, but very slowly, over a long period marked by lot of volatility.
Also it's only trustworthy as far as everything happens on the blockchain. Once you step off it for even a second, it doesn't help. Eg, witness the absolutely amazing number of scams happening in the area, and the number of well known, and supposedly trustworthy services suddenly crashing and burning.
Re: trust the devs: do you trust the electricity in your house? What about the wires in the wall? Do you trust others to follow traffic rules?
Eg, I had a passing interest in BTC, but I my interest was in the very old school "buy pizza with it" kind of use. That usage is of no interest or importance to the current BTC system, and it doesn't matter one bit how many of me there are.
The people who matter are the people who commit to the repo, the people who run miners, and the people who run exchanges. The desires of the 99.9% who aren't any of these are nearly irrelevant.
IMHO, the dust has already settled and been washed away by the rain water..
