True, Ethereum is in the lead for now.
A high market cap can also be a curse, because a lot of the community will sit back and take it easy, thinking they've already won the race... When in fact there are dozens of competitors working their asses off to innovate and build an even bigger community.
So the cycle continues, the complacent top dog getting unseated by the hungry underdog. Too much wealth can get into your head making you believe that your work is done. I think it's great to have a competitive landscape and seeing the innovations unfold potentially revolutionizing how things are done.
