The same is not true for Dash because there isn't as much confidence in its longetivity. No-one is trying to get Dash for cheap prices (for example) because it doesn't project the same amount of enthusiasm.
Monero is more free market due to its wider distribution, thus being such a small cap, it will display more bidirectional volatility than a manipulated market. As an advantage, it has more true liquidity, since I presume much of the exchange volume in Dash is insiders buying from themselves with a bot.
If you are a whale, you can't buy and then sell Dash. Not enough liquidity. Your only option is to sleep with Evan.
