There have been two major bubbles so far.

The first one was in June 2011. The price rose by a factor of about 40 in two months before it fell back to about 3 times where it started.

The second one was in April 2013. The price rose by a factor of about 20 in two months before it fell back to about 4 times where it started.

The latest rise started about one month ago and has risen only by a factor of 2. If this is a bubble like the previous two, then I expect the price to rise to $2500 - $5000 over the next month and then crash back down to $375 - $500.

I'm assuming you mean the distributed exchange. This is software you will have to download. I'm told it's ready for linux and macs late next week. Windows shortly after.

There is already a homepage up and running. mastercoin.org.
