with that rate you're not making any profit, it's better to leave mining where it is and investing in bitcoin directly, it will reward you soon
I'm a miner at heart and always will be. But I have to admit I did do a little buying of coins. When I sold my last gen gear I saw either I could buy current gen... or wait. And waiting is had hard for me as it's no fun having lower hashrate.
But I ended up buying coins and holding. I plan on buying next gen miners with it. I'm hoping I will see value go up a bit and I can make some off of that... then buy back in. But hard to say how lucky I will really be.
