I don't know about Google but I have used this guide https://github.com/ideashavenoborders/grin-cloud-mining/blob/master/README.md to CPU mine. It's expensive but I like the fact that I can mine some GRIN on CPUs still. Even though the reward is low. I think Grin will be at the ranks where Litecoin has lingered for a couple years. Short term I believe it's best to buy it once it's traded below $1. In the long term I see it at $10+. I believe that Grin will boom even more than dogecoin. It's private ecash. I'ma use some and save some as they roll in
