So I understand that bitcoins are discovered/rewarded/found by mining. From my understanding that is the only way they are discovered/rewarded/found and put into circulation. Then when you go to a MSB to purchase bitcoins, where do those bitcoins come from? Is there a miner out there that sells bitcoins to the user via Walmart, CVS, Western Union, etc? If so, what is the incentive for that miner to continue to sell the bitcoins? Contracts??
Or maybe the stork brings those BTC
