Does anyone know the most profitable cryptocurrency to mine using a foss miner?

I want to use Zcash as my daily cryptocurrency but for mining, I might want to mine some other cryptocurrency as Zcash would be a very difficult currency to mine. So I am looking for a very good mining software which is foss and can be imported as a library into my own code which supports a very easy to mine cryptocurrency, and then I would trade it with Zcash. Would anyone know what it could be possibly?
