No, The total daily mint of GRC is equally split by project.

Moo can be run on much less powerful systems hence can be a good starter for people.

The projects cannot change the amount of mag they generate, this is fixed by design of the blockchain. The entire point is FUD.

Edit: To expand high end hardware tends to be put to use on other GPU projects where low end hardware is either unsupported or just not competitive, therefore running Moo, or Collatz or another project that supports low end hardware means they are mainly competing against similar low end hardware.
