For long-term gains should i stick to ETH or RVN ?

At the current moment, i have ~85 Mh/s when mining ethereum and around ~48 Mh/s for raven

If i wanted to mine and sit on a coin to make me the most gains and enjoy the massive growth of my portfolio, which coin should i mine.

i know this is the subreddit for Raven but im curious to see what people think.

i have around 600 RVN and 0.037 ETH
