It looks like there is some very real competition between ethereum and bitcoin.
Take out the name calling and the haters. The people who think there should be "one blockchain to rule them all." When you do that, you see that both have support from very powerful players within the crypto space and beyond.
What's more. no one really seems to know what the future will hold between these two blockchains. Will they succeed side-by-side or will one replace the other?
Can you compare these two technologies to previous competing technologies? Is Bitcoin MySpace while Ethereum is Facebook?
