I've been actively researching use cases and properties of cryptocurrencies (more than 15 minutes) and have come to the opposite conclusion: none of the hype is based in fact. For instance, let's go through your claims one by one.
> Decentralization,
There is surmounting evidence that this is not true and that Bitcoin and Ethereum are actually quite centralized and would benefit from being more centralized [0][1][2][3][4].

> immutability,
I'm not sure if you've heard of theDAO fork [5], but basically transactions on Ethereum are not final. They can be reversed if a select group of powerful individuals decide to do so. Maybe it's "immutable" in the sense that the history can't be changed, but it's not "immutable" in the sense that the history can't be reverted arbitrarily by someone other than yourself.

> protocols monetized with market forces,
What do you mean by this? Older protocols like TCP weren't made operational for free, they were funded by many institutions, both public and private. Are you sure this is something new?
> fee-less payments that cannot be prevented
Cryptocurrencies aren't fee-less. There are transaction fees, exchange fees and volatility/liquidity risk. If you're in the US and want to send money (real money) to your friend in Japan, you must buy crypto (exchange fee), send it (transaction fee), and sell it (exchange fee and volatility or liquidity risk).
Finally, as you've seen with theDAO fork, crypto payments can be reversed, which prevents the transaction from being final. I'd love to see any research on how crypto payments can't be censored, though, if you have any.
