Now this maybe a little bit fishing for excuses; but let me give you another positive thought:
Wherever you earn your Gridcoins, you can (and should) certainly pipe a percentage of that back into research or other ways of "doing good for society" (or simply provide computation to the projects you deem socially promising at a larger scale).
I assume that most Gridcoin miners / crunchers are from the research community, or really close and in support of it, so it is actually THE ONE crypto community where I'm quite convinced that enough whales would do good with their gains, making the whole pyramid-schemeish nature of blockchain cryptos feel less bad than with other coins ... for whatever it is worth. Thanks for your ongoing contributions!
