Hi All!

My first post.  Lurking around for awhile. Very thankful that I invested almost 10 bitcoins to buy AGS back in early 2014. Now it has grown to an amount that changes my financial situation.  Much appreciation to the founders and core devs for the continuous development!!

Question to those in the know:  What factors caused the 61 million dollars worth of BTS traded hands on Jul.23rd, then the fall back to earth the last couple of days?

Unless I missed something from the state of the network report?

Hope someone can share some insight!
