I have seen many good looking graphs that compare which cryptocurrency is the best. And investing into some coin which is not in top 100 only because they say that they are better than others...
Ethereum has more developers, more funds, do you think that they are not smart enough?
But ethereum is better than anothers altcoins my friend,, even this is the best altcoins for now
Ethereum has strong community,, and remember community is very important things on any project of cryptocurrencies..
