Its a good point to bring up because of the buzz surrounding the Famous Gravity Well. Correct me if I am wrong, but this is to prevent mining pools from busting in on a low difficulty coin and ramming it with an insane hashrate before its block difficulty has a chance to ramp up. Once it does the pool leaves a barren wasteland of high difficulty blocks which cannot easily be mined by the little guys anymore until the diff comes down (at which time the pool may return to wreak havok).

If we look at CGB, we see that it has already matured beyond this volatility. Proof of Work mining which the Gravity Well protects, is no longer a major target for miners in CGB. We are almost at the point where the block reward will be 0.01CGB indefinitely. This reward is intended to give just enough incentive to Proof of Work mining which works in conjunction with Proof of Stake minting to secure the network, and provide savers with interest. In short, CGB is past the point of high volatility caused by mining.
