To clarify, I was highlighting the distinction between:

[1] encryption

and

[2] digital signatures

I cited a presentation where Vitalic Buterin stated categorically that there was no "encryption" in cryptocurrencies - rather they work use hashes and digital signatures (in Dash, blind signatures).

I wrongly paraphrased his statement as saying "there is no cryptography in cryptocurrencies" instead of "there is no encryption in cryptocurrencies".  A few posts later, I corrected myself and acknowledged the misquote, at which point I got (predictably) lambasted for being clueless about cryptography (Digital signatures and encryption are different branches of the more general term 'cryptography').

Here's the clip so judge for yourself the gravity of my misquote. In fact when Vitalik asks "anyone see what's wrong with that title", an audience member answers "cryptography" and Vitalik replies "Yes", however the more specific branch thats relevant is encryption.

Here's the clip (You need the sound up):
