The Dash scam was easier on the development side because of the btc/ltc code copy paste. It has a shiny wallet long ago and the code is easy to integrate everywhere .That's why btc whales decided that it is better to pump it than Monero. Monero is harder to develop but has way more potential and will eventually be the one and only Cryptocoin.
When will XMR surpass Dash again? Last big pump cost more than 100000 BTC to get last ATH. But Dash has much less volume, their pump is crazier than us.
You do realize that this is its weak side too. Only few followers and few users besides the masternodes, PRs

, and the devs. Pump is because of the btc whales getting too f***ing rich and wanting a hedge coin. Nobody uses or will use Darkcoins(I like how they started anonimity oriented and when they saw that it can't compare with Monero, rebranded it, showing that it's just easier to use).
