The thing that's shocked me the most is the amount of money raised by ICO-type projects during the boom and the fact that not one of them appears to have delivered anything. I'd expect some to be scams, but every single one of them? Not a single reputable functional team raised money with an ICO and shipped something?
I'm excluding ICOs that shipped things of use only to other ICOs, cryptocurrency, gambling, and speculation. That's self-referential: crypto to make crypto for more crypto. I'm talking about things of use in the real world. That's why I called it a parody of financial capitalism. The point of money is to facilitate useful things, not to just chase itself around in circles. The latter is the essence of financial capitalism vs. real productive capitalism.
Ethereum's ICO was in 2014, and most ICOs were on Ethereum and are less than 1-2 years old. One of the older "smart contract" projects has been in development since 2013 and it is still a massive work in progress.
You have a shit ton of people who want to reap the benefits of what-to-come, in fact that is what ICOs made easier. What it lacks are extremely competent people willing to dedicate anywhere between 3-10 years of their life to make it happen. It is hard to say you can buy that with strictly money.
I've thought it was overvalued for a while but I still kept expecting the whole ecosystem to create something I or someone else might find useful in the real world. I've waited and waited and waited but no. Teams of brilliant people, tons of money, and nothing!
It started as a sort of crypto-libertarian critique of financial capitalism, but then it seems to have evolved rapidly into a "reductio ad absurdium" parody of financial capitalism.
Among other things I think this experiment proves that the excesses and absurdities of financial capitalism are not a technical problem. They are a social and political problem. The instant cryptocurrency got legs it became yet another speculative casino just like the rest of the financial system.
Edit: so prove me wrong. Does anyone actually use a cryptocurrency based system for anything other than cryptocurrency itself, speculation, or gambling?
