Those Singer quotes almost killed me: "limitless ignorance of swaths of the human race". He's absolutely correct, but, deep down, secretly a little upset he did not purchase Ripple at 2 cents
There is perhaps a bit more to cryptocurrencies that Singer gives them credit for. I've recently been reading some of the original stuff from Szabo / Satoshi eg http://unenumerated.blogspot.com/2005/12/bit-gold.html and https://bitcoin.org/bitcoin.pdf that partly explain why they have worked and not collapsed 9 years later. A lot of it is much clearer than the hype which has followed.
It's bait for people to jump in a pool with sharks. People like Singer and Buffett are driving by in a boat and looking in with binoculars. Hopefully enough people do not jump in that there ends up being a tidal wave.
