That's exactly what I worry about. It's only speculation as to how the market will react. It could be treated as 2x the coin for the same hash so the value of each drops.  On the other hand VTC may hold it's value while Monocle has it's own value which may be nothing or may be more than VTC.

It will be interesting to see how the mpos pools react. There is already some talk about implementing Monocle. My guess is sometime with the first week of being introduced we will start seeing mpos pools with merged mining.
