Couple of videos I made back in 2015 about the various BitGold solutions.
The first video is a general introduction to the concept BitGold:
The second video is a "review" of BitShares’ BitGold solution:
The idea was to create a site, www.freebitgold.com that would serve as a platform to review all the different BitGold solutions that were emerging, while positioning BitShares prominantly as the most open and decentralized solution.
Unfortunately I never had time to develop the idea, so the site has been sitting there idle now for 12 months or so while the BitGold industry has been blooming.
If anyone wants to help develop or even buy the site comment or PM me.
