None of it ever makes any sense to me.  But keep in mind that pumps are hard to do with Dash.  So much of the coin is tied up in long term Masternode holders, and this seems to have an effect on prices.  We are not at all exciting to traders, hence our price remains low, probably until adoption starts to take off.  At that point, market pressures should bring up the price.  But almost all of the market is speculation and gambling.  So, no.  Unless you want a steady income by buying a Masternode, or buying into a group Masternode, I would not speculate on Dash for short term gain, personally.  You could sell when you think it's high, and it just keeps going up, buy when you think it's low, and it keeps going down.  It makes absolutely no sense, and the swings are generally very small, so you're better off earning 14% a year by holding a Masternode or playing the market elsewhere if you're good at that
