So after reading 7 answers to my question I have concluded that 1 BTC =100 million satoshie, and there is NO pool of BTCs for sale  and all selling or buying takes place on the block chain from a wallet that is on the blockchain. As for new BTCs that are created by the miners, My guess is those are sold to someone that has a wallet on the block chain. Sounds like a closed loop of an operation? So could a billionaire buy a million BTCs and try to pump and dump BTC to control the value like they do in the stock market Dark Pool? I am learning a lot here. Thanks for your inputs.
