Yes and no... Profits are made into USD and not bitcoin, so if bitcoin prices drop when you cash out you get more bitcoin ... if bitcoin price rises you get less. I like the "income" stability... In a downtrend market it looks like a profitable solution. Because you decide when to cash out into bitcoin.

I was mining ZEC but ZEC was dropping more than my profits in the last 2-3 weeks.. so no real profit.

I will git it a try for a week or 2 to see the benefits.
