Quark is going from strength to strength. It may not always look like it on this forum but that is because we have been focussed on building up the community and developing Quark's infrastructure; publicity and marketing have not been our strong points so far. However, there is a LOT happening. We have recognised that we need to do more awareness-raising.
Quark is going to be huge: It is incredibly fast and it is the most secure coin there is, at a time when the security of cryptocoins is becoming a major issue, and transaction speed will become an issue for any coin that wants to move beyond enthusiasts and into the mainstream.
There is still time to get in. The price has taken a knock along with all the other coins and a lot of people don't know just how uniquely good this coin is...yet.
