What do you mean?
There is around 50 % less Darkcoins (6-7 mil) issued compared with Monero (12 mil) so it should be easier to pump Monero's marketcap. Each 1 dollar rise represents 12 million dollar rise in Monero's and merely 6-7 million dollar rise in Darkcoin's market capitalizations.

Hes talking about what I like to call the ripple effect (since ripple is the poster child for this bait and switch). The price is a function of supply and demand (obviously) but coinmarketcap conflates currency supply for actual supply on the market.
