This depends on your moral framework. A large part of moral culpability is proximity. How close are you to the issue at hand, and how easy is it for you to take/not take some action. For example, worrying about poverty in a country on the other side of the world, when there are homeless people sleeping on a bench on your street. I can't possibly convince a mega corp to stop wasting energy, but I can try and waste less myself. I can't stop people from using Bitcoin, but I can try and develop/advocate for better alternatives. When all is said and done, is it better to have shrugged and done nothing, or done what was within your power to do? "All we have to decide, is what to do with the time that is given to us".
