Dash is certainly doing really well, but that's a bit of a click-bait title! Dash is nowhere near Ethereum, it's barely a tenth of Eth cap - unless you mean individual coin price, which isn't relevant unless you take supply into account too.
Well done Dash though. I don't have any, and wish I had!
I'm very curious, why do you care more about the market cap than the individual coin price? As an investor in individual coins, why do you care about the overall market cap?
