coins that have never been mined will not give profits to crypto users,
what OP is asking has nothing to do with profit so it is not related to non-mineable coins.
there are different ways of distributing the supply, one of them is mining the coin using proof of work algorithm which bitcoin is using this design. other methods can be different but they are not necessarily bad just because they are different and you should not confuse them with a premined altcoin that the dev is controlling it to make free money.
