Hello!
It's a great exchange you created using MEAN stack
Node.js rocks !
I've been trading DGB/BTC and it went really smooth and fast.
Please add SkeinCoin (SKC) and SocialCoin (SOC).
The first one (SKC) uses unique hashing function - Skein (SHA-3 finalist) that makes it different from many Scrypt and SHA-256 bitcoin forks.
Skein is more energy-effective than Scrypt and can be mined on CPU's and GPU's.
SocialCoin is aimed for charity and all of it's pre-mine is going to be donated to charity organisations.
So, the more it costs, the more will be donated.
Thank You!
Looking forward to seeing many currencies on your exchange.
