That's a fascinating thing that WBTC is proposing to do and could become a good model for how coins from various popular chains could be used on the newer innovative chains, such as EOS. It's interesting that some of these projects put these coins in "cold storage" while others put them into a "black hole". What do you see as the advantages / disadvantages of each?

A last thought re the quintric, it's interesting that it wasn't on bitshares as a tradeable coin - I've seen Stan Larimer @Stan promoting it on @BlueRockTalk 's show (and @Stan calls himself the "godfather of bitshares" - which, I think, means he's a major witness/BP and innovator for bitshares). Could it be that there's just not enough circulating volume of the quintric coins yet for there to be trading pairs on bitshares? I don't know how all this works well enough to fully understand this - which is why I will likely take some of your courses when I have the time to devote to them :-)
