Those two coins are nothing like each other. One is a clone, the other a genuine piece of original engineering which has overcome some very difficult technical and commercial milestones.

CLK's market cap is consistently around a quarter of DRK's, so if DRK doubles, CLK may double. If DRK halves, CLK may half also, but the relative valuations aren't going to change much. If either of them gets dumped permanently (the way, say CINNI did) it's going to be CLK not DRK - not because it doesn't have good fundamentals but because they aren't distinguished enough for it to overcome such a huge disparity, especially when there's such an active competitor.
