I point it to XCN because so far, XCN is the one that gives me the highest profit that I've found. And partly because I believe it can still grow. But mostly because it's more profitable compared to the "usual" coins and I haven't found anything that consistently give me a higher profit than those.

I prefer a little bit of both - I enjoy profit, but I also enjoy keeping a coin alive, or believing that a coin has what it takes when it comes to specifications etc. and would like it to grow even further.
