So he concluded that the Scrypt algorithm somehow gave a coin it's value? That doesn't even make sense and makes his conclusion suspect. Bitcoin dwarfs all other alt-coins combined in terms of pretty much all those factors and does not use the Scrypt algorithm, therefore the Scrypt algorithm has absolutely nothing to do with it.
Here's a link to the episode:
https://letstalkbitcoin.com/blog/post/the-bitcoin-game-18-jeremy-gardner-adam-hayesHe looked at "66 commonly traded altcoins against bitcoin". So in his analysis, of those alts, Scrypt algo apparently did better over other algos.
I'm not sure what time period he used, but you know crypto - much can change quickly (see $UNO hash rate). I think he did solid work using the data he had available to him at the time. From the sound of it there was visual info accompanying his presentation - I'd like to see the $UNO data. As it is - I thought the info was very positive for Unobtanium.
