user139175: Is new supply of bitcoin only brought about due to miners selling their mined bitcoins or does the mining process distribute bitcoin back into the system in addition to the miners reward/transaction fee?

user5406: The block reward consists of two parts, the transaction fees that are paid by users to the miner that confirms their transaction, and the block subsidy, of freshly minted coins. The only way new coins were ever added to Bitcoin's money supply is per the block subsidy. Hence, all coins in the supply were at some point found by a miner and then put into circulation when they spent or sold them.

user48884: Newly generated Bitcoin go only to the miners that find the blocks. In order for the new supply to be circulated, those miners will need to sell the Bitcoin that they have earned.
