ETH first, then Ripple, and then Dash.  Eth just has so much going for it in the sense of practical business value.  Just look at all of the ICOs that run on ETH and you can see the unique ecosystem that makes ETH so durable going forward.  I don't know why ETH values still fluctuate so much in tandem with bitcoin but my opinion is that this is simply a maturity and psychological reflection.  Eventually, this will stop and ETH will be recognized as independent and wholly separate from bitcoin. 

Dash just has too much pressure from other masternode coins.  Dash is still the lord of the flies in masternode land but there are many other contenders that are gaining market share.

Ripple... well, it's just printed but it's printed with a purpose and the threat of mass adoption in the banking industry puts this just ahead of Dash but clearly behind ETH, bitcoin... and probably many others.
