I'd say you should stick with Ethash algorith as your card is better when mining Ethash. You just barely started mining. If ever there are price fluctuations, and since you are just a beginner, better let nicehash do that for you. If you are using nicehash, it comes with a feature of auto switching to the most profitable coin to mine but times when there is much price fluctuations, I see there maybe a little bit of profit loss due to the auto-switching. If you ever wanted to switch, try to focus on a coin for 1 week and then decide if it is worth mining.
