I have done a lot of activities in video games that would require significant CO2 emissions in real life. Potentially millions of tons. So yes, it's much better. There is also a significant population of software developers that picked up programming because of video games. Economic simulation games can help you develop an intuition on how to run a company and how they work without having to risk starting a real company with the potential to fail and ruin you financially.
Meanwhile the only worthy claim that Bitcoin has is that it's a middleman for central bank money. Yes it probably funded a lot of good economic activity, but it's the job of the central bank and government to do that. If they didn't fail then Bitcoin would have literally nothing to do.
