So, who isn't? Look throughout the blockchain ecosystem and all you will see are scams, illegal activity and get rich quick fools. I have personally yet to see a use of blockchain tech for useful legal purposes. Yes, you will see some companies "announce" that they are "investigating" blockchain or whatnot to get some free PR, but you don't ever see them actually release anything useful.

(I fully accept that blockchain has revitalized criminal enterprises such as child pornography, extortion, and Ponzi schemes, but I don't see any reason to celebrate that).
