You will get a highly experimental token, that is not expected to gain any value, in return. These tokens do not hold any value. These tokens are not expected to increase in value, especially not by the work of others. You are donating to help the project grow and not to get tokens in return. What you are getting in return is a valueless utility token. A utility token can be useful as a way of keeping track, but it's not something to be traded or speculated on.
