I think about idea to create a blockchain where everybody will be able to mine a new bitcoins (or just altcoins of this project), by performing some action witch can be performed only by a human..  For example, some capcha solving etc.  In case smb do this action he will get a coin for it. So the total issuance of the coins is unlimited, but creating a new requires doing work.  So creates some value.

Does anybody has some opinion about perspectives of my idea?
