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.
Ethereum is succeeding already, throughout the world. With just a few years of its presence and it has already broken the records of bitcoin.I think it has a good chance of being the future of blockchain technology. Many of the innovations used in the Ethereum blockchain are being replicated and improved by other blockchains and founders.
