Bottlecaps Early History:
As far as I remember off teh top of my head Bottlecaps was created by BitJohn and Mullick from Cryptsy.  It was one of the first Scrypt + POS coins.  Ticker was originally BOT then changed to CAPs.  That is pretty much all DigitalIndustry had to do with CAPs is campaign for the change from BOT to CAPs and provided the nice Fallout graphics.  Tranz took over CAPs because Mullick all but abandoned it and has done an excellent job with CAPs as with HBN.  For what its worth DigitalIndustry didn't have much if anything to do with Quark in the early months either, I do not remember much from him in regards to Quark until Nov 2013.

History might get blurry when told second hand but start at page1 of a coins thread and its all there.

Silvermetal is a deranged anti-Quark troll that now follows DigitalIndustry from thread to thread, and is caught up in a 'beautiful mind' type conspiracy where everyone is a sockpuppet of DigitalIndustry.  Pretty much every Dev from 2013, every person who posts against him, and even Shaquille O'Neil (because he made a video promoting Quark) is apparently a DigitalIndustry sockpuppet.  It is really messed up and weird.
