not in marketcap, no never.
ethereum is only good at one thing and that is having a huge marketcap by manipulating numbers. and it is pretty simple, ethereum has
89.5 million coins available versus Dash's
7.1 million coins and in order for dash to even come close to that number is to be worth $248.38 and that is just not possible

unless Dash produces some new coins out of nowhere and turn than 7.1 million into a 10x more number to be able to compete with the Ethereum marketcap manipulation and become the number 2 marketcap manipulator!
