1st, There is only 9.5 billion on the market right now. Ripple has 39billion in circulation, and has a price of 40 cents. So from now until June XLM can rise more then ripple. XLM can go to sixty cents on any big news.

2nd, Jeff McCaleb is competing with ripple. In order to compete and maintain the strategic vision of ripple he will have to lockdown the remaining supply or about 65billion in stellar.

3rd, He will most likely buy back XLM. Why would he do this because it would attract investors from ripple into Stellar increasing the price and Market cap of Stellar possibly beyond ripples. Bringing him to number #2 next to Ripple, and once he does this he's on the cover of Forbes.

4th, It doesn't make sense for anyone to sell XLM to receive Bitcoin and then XLM because what you receive is a very small amount of XLM.

5th If any announcement comes out that hes locking down XLM or buying back XLM this thing goes interstellar. 🚀🚀🚀🚀

It has to be done to ensure the vision of the company.
