Please add a Cryptographic Anomaly (CGA) coin. It will be the anomalous coin on your exchange. You will not regret it!!!!

Cryptographic Anomaly is a modified clone of Litecoin, which is a lite version of Bitcoin using scrypt as a proof-of-work algorithm. It may become one of the rarest coins that has ever been made, if not the most elusive.
Yes I know about these other "so called" rare coins (such as 42 and Ron Paul etc.), but in my eyes they aren't rare because you can project how much of the coin will be generated at any given time. With Cryptographic Anomaly the normal block reward is zero, it uses the modulo operation to find the remainder of the current block number divided by the current difficulty. If that remainder falls between 1 and 0 then the block reward gets changed to 1 for that block, thus an anomaly is born. By using this algorithm it becomes impossible to project how many CGA will come in to existence at any given time, which gives us our "truly rare" or elusive coin. The block time is 40 seconds and the difficulty refresh time is every 2 blocks. The max coins will be 10 billion (but that my take eternity to fill).
When the coin was first launched it was brought to my attention that if the difficulty was 1 or below then the odds of generating an anomaly was more or less 1/1. That means that almost every block was generating an anomaly. This defeated the purpose of the Cryptographic Anomaly so in a recent update I had "raised the stakes" and made it so that once the coin had hit block 15,000, and the difficulty continues to be below 3, the MAX probability of making an anomaly will be 1/3. That means after block 15,000, and the difficulty is below 3, 1 out of 3 blocks will generate an anomaly. If the difficulty rises above 3 then the normal modulo operation will take effect.
Another problem we were having was that the difficulty was fluctuating at inconsistent rates. So in a recent update I had implemented Kimoto's Gravity Well in order to smooth out those fluctuations.
