I've been questioning WDC a lot lately too. It seems the entire future of WDC is based on Scharmbeck and a few other qualities that virtually all alt coins have now (fast transaction times, large supply, etc. Soon, I don't know if even Scharmbeck will be much of an advantage, as cryptsy should be accepting USD at any time.
The piece that seems to be getting the least attention, and that should be getting far more, is the merchant tools. As a merchant myself I can tell you that the only crypto-currency that I would even consider accepting right now is BTC.
I have to agree that the main focus at the moment should be the merchant options. Scharmbeck is a great way to allow people to buy directly into WDC and sell WDC to $'s.
As the chap above rightly mentions, most people will only accept BTC as a valuable payment. Would someone accept an altcoin knowing that in a week it could half in value?
WDC has to put itself into a position where it is a trusted coin where people can happily accept it as a way of taking payment. After watching the market over the last few weeks, WDC has been very stable. I believe this is a good sign.
I think one of the reasons WDC isn't increasing in value at the moment is because there are lots of people mining and autoselling the coin.
Once Scharmbeck is released to the public, WDC only requires a handful of websites to accept WDC as payment through Scarmbeck's merchant options and the coin could quite easily take off..
