I'll edit this post as time goes on to add information, but I won't delete anything.
2013-05-19:  I think we will reach a high of $221 at some point from now until the end of the year, and then break through $360 around Spring of 2014 like a hot knife through butter.   I would love to see bitcoin reach $500 by year end, and there is a very good chance it will, but I'm usually wrong so I'll stick with $221 for now..
