BTC38 was going to implement Quark but volume was too large and they delayed the trading. When their system is ready for that volume they will add it. It's a great time to stock up on Quarks after the big crash of pretty much everything in december. Quark is one of my top 3 bets in the year to come.
volume to large?
I wish that was the case. But have you looked at the volume of quark at vircurex.com lately? It rarely is more than 10 BTC a day...
At the moment it's only at 2.7 BTC...

I think he's right. I'm had difficulty with btc38 website yesterday.
So they're struggling with CURRENT coins.
