How many RabbitCoins have already been generated?
The OP says there will be a maximum of 100 Billion, and I 've seen about 5+ Billion on the open markets.
Reward: (Random)
Block 1-100,000: 1-1,000,000 RabbitCoin
Block 100,001-200,000: 1-500,000 RabbitCoin
Block 200,001-300,000: 1-250,000 RabbitCoin
Block 300,001-400,000: 1-125,000 RabbitCoin
Block 400,001-500,000: 1-62,500 RabbitCoin
Block 500,001-600,000: 1-31,250 RabbitCoin
Block 600,000+: 10,000 (Flat) RabbitCoin
Given the above from the OP ... We can take the current height of 3478234-599,999 and multiply by 10,000 reward. Then adjust your best guess for blocks 1-599999.
at least, 28,782,310,000
