Interesting topic these days, Google $300 trial for computing engine and how it could be used for mining.

Register for free trial at: https://cloud.google.com/free-trial/ - get $300 worth of credit.

Now the problem is, terms and conditions that state:

Limitations. During the Free Trial:

Customer’s use of Google Compute Engine is restricted to only eight cores of concurrent usage per Free Trial (as further described in Documentation);

Customer may not use the Services to engage in mining cryptocurrency;

Certain Services and features will not be available under the Free Trial, as indicated in the Google Cloud Console; and

The SLAs do not apply.

However, it also states the following:

At any time during the Free Trial, Customer may convert its Free Trial account into a standard Google Cloud Platform account by clicking the “Upgrade” button in the Google Cloud Console.

If Customer upgrades to the standard Google Cloud Platform account within 12 months from the Free Trial Start Date, any remaining credits will continue to apply and will expire 12 months after the Free Trial Start Date.

and will expire 12 months after the Free Trial Start Date. Customer’s continued use of the Services after upgrading to the standard Google Cloud Platform account is subject to Customer’s compliance with the Cloud Platform License Agreement (or other applicable agreement between Google and Customer) and the Free Trial Terms and Conditions will no longer apply.

Which means, your 300 is still available after an upgrade, but you are allowed to mine :)

I did not find anything in https://cloud.google.com/terms/service-terms that would violate TOS.

Happy Mining!
