All coins make the same amount of profit per day. People use monitors that monitor profitability and they switch to the most profitable coin to make an extra %'s.
No secret to this. Unless the coin is unlisted and then nobody mines it, but that's a gamble.

They don't all really earn the same amount. If you choose the right one and the value goes up dramatically then it's more profitable. I remember getting in on Zetacoin years ago and making a tidy profit on that, and that was back in the old Block Erupter days
What you are talking about is speculation.
But at the current market rates and current difficulties all coins have the same profitability.
