So you can buy altcoins, and if you look at the Vircurex markets, sometimes you can find a loophole where you can buy the altcoin for cheap on MCXnow, then use the altcoin to get cheap DVC on Vircurex. Then take those Devcoin back to MCXnow to make a profit. You really have to pay attention to ALL of the devcoin markets at once to do that though.
Keep in mind Vircurex has posted the following in their news section:
"on November 3rd 2013 we will be disabling the Any-2-Any coin trading, as from then onwords only trades to and from BTC will be supported."
Is the Devcoin code nto going to be updated anymore?
