The 'killer app' for the time being are indeed ICOs. Unregulated, messy ICOs.
I do think it is too early to judge the cryptocurrency world or blockhain in general for not having 'killer apps'. Analogies to the early internet are no good either since there is no reason as to why this would behave like that. Time will tell. Can't deny it is an interesting space!
During the internet bubble fundamentals didn't matter because it was a new economy, valuations shot up, everyone was seemingly raising a lot of money to be the next best thing and then the music stopped. Reasoning of the form "this seems crazy but it must obey different fundamentals we don't understand so let the music keep on playing" should make us uncomfortable.

I'd actually disagree exactly because of the lack of "killer apps". There are plenty more interesting things happening in technology when you consider no one really seems to know what to do with this. Right now blockchains sound like get-rich-quick catnip for geeks.
