Blue Chip Bonds is a new Bond game using BCHIPs

with earning opportunities avaliable for players actively engaged in the game.   Buy a bond and reap the rewards from other players as they buy in.

The price of your bond automatically increases 25% once you buy it.   You earn yield until someone else buys your bond.   Then you collect 50% of the gain.

45% of the gain is distributed to the other bond owners.  5% goes to Wall Street Marketing.

The yields are based on the relative price of your bond.  If your bond is priced higher than the average of the other bonds, you will get proportionally more
yield.  The current yield rate will be listed on your bond at any time along with the price.

The bonds have a half-life.   When the half-life is reached the price of the bond is cut in half.

A bonus referral program is available.   Using your Masternode you will collect 5% of any net gains made during a purcchase by the user of your masternode.
