I have seen clear structure and numbers on how baking, delegating and double endorsing etc. affect to the users amount of Tezos, but is there any cost on making a contract (in other words creating content stored in the block chain)? And is the flow into your wallet or out of it?
If baking gives you money, how about the gist (contracts) that feed the baking process and make the result thus bigger? (sorry baking metaphora extension)
