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.
Of course I agree with you. It seems to me that Ethereum is the crypto currency that we will pay for all the necessary services and purchases in the future. This is exactly what we really need for the digital future
