This is an exchange website right or is it an altcoin. Darn, sometimes people here are so deep with their words. I will just google that rolling peg thing.
It is both actually, but funsponge was talking about the coin I believe.
I doubt you will find much about rolling peg by googling it. It has never existed before. Funspunge is wrong about this being used by the banks.
The trouble with traditional pegs, or hard pegs, is that they tend to break. The last big one was the swiss franc. And when they break it can do quite a lot of damage. A lot of countries have therefore started to use a more flexible "peg". This is what BitBay is doing too. Only BitBay is able to do it much more efficiently than countries because it can change the money supply instantly whereas countries must do it over months and years. BitBay's peg also gives gives a new advantage called "user value protection" (UVP). I'm not going to derail this thread by getting into all the details, but if you go to BitBay thread you can ask for the specifics there https://bitcointalk.org/index.php?topic=890531.2860
