It seems that a lot of people don't trust QRK. Supposedly largely premined and controlled. Personally, I just don't really believe all the QRK hype, and I the value hasn't risen significantly over the past weeks, so low on my interest-list.

Earthcoin looks promising. I like the ideas, I like the enthusiasm, I like the coin-design  Also, EAC is a LiteCoin descendant.
It will be interesting to see what the value does once it hits exchanges. EAC has a high difficulty, so that might be an indicator for a quickly rising value and a fast uptake by the community.
