ETH will allow $2T of underground economy to become more structured (and possibly less underground) through DAOs.http://www.washingtonpost.com/blogs/wonkblog/wp/2013/04/23/americas-2-trillion-shadow-economy-is-the-recessions-big-winner/If it captures 1% of that $2T, it is equivalent to $20B, which would put ETH somewhere around $150. Those who sell for $2 will shit bricks, eat sand and may even commit suicide in the years to come. If it captures 10% of that ETH will be $1500. I know it sounds crazy, but so did the Internet in 1995.
Once it's launched their main focus will be on scalability, which I think is the real reason crypto is not ready for mainstream. Once they can handle 100K TPS (and I'm sure they will), it's game over.
Well it's true that both etherium and Bitcoin cryptocurrency are doing really well in the financial markets and both of them have immense potential. But I don't think that etherium is better than bitcoin and I don't think that it's the future over Bitcoin as Bitcoin is way more popular and has way more users and acceptance all over the world than etherium.
