I don't want to be a party pooper but I've watched the charts and orders on Bittrex for several days and I think someone buying his own coins to inflate the volume. Right before a market buy of > 0.3 BTC, a sell order of the same size appears. With only 1 BTC, the equivalent in viacoins, a bit of time (and trading fees) to lose you can add 40/50 BTC of volume without having to buy any new coins in the end since you're buying your own coins.

If we start seeing real buys I'll be more confident but right now you shouldn't jump on conclusions too fast.
