The last 4 years has been the "Alpha", now we are in the Beta.

Bitcoin won't know it's true value until you can spend it virtually everywhere, on every continent, in every country, including person to person transactions using cellphones and ATM machines. By the end of 2014 we may then be in the mainstream phase, and having to watch out for the real speculative bubble.

I'm thinking $7,000-10,000 per btc.

If it survives the next wave then who knows, $100,000 or more.

This is in the rhealm of possibility but by that point there will be heavy competition. At the momeny alt coins are a joke but the "2nd Generation" is showing some promise. Nxt tried but was more of a scam than anything, Protoshares a great idea that is showing some promise, CGB is a very unique idea that has yet to be fully released, and as a beta tester of Emunies, looks like a combination of all these things and is about to blow the top off when it get's released. It's going to rock the boat and unlike other alts not feed off of bitcoin's success but draw in crowds independently.
