I don't think it's easy (nor ethical) to monetise the crisis directly, but some forms of income are resilient to it. Some products and services are needed at all times, and you can earn a commission for promoting those.
For instance, people still go through my website to understand various aspects of German bureaucracy. They open bank accounts, get health insurance, get liability insurance and so on. They get help free help, and I get paid to provide it. It's a nice business model.
Many freelancers have lost their income because of the pandemic. I plan to write a comprehensive overview of their options. It might lead some of them to get things they genuinely need: disability insurance, private pensions and so on. This benefits both my readers and me.
Software development is also largely unaffected by this crisis (although the companies that employ them are). I wanted to finish this contract in May and ride into the sunset on my motorcycle, but with Europe shutting down, I'll keep working for as long as I'm needed.
I also use the shutdown to save money. I have nowhere to spend it anyway. I don't commute anymore, so I always eat at home. I use the 2 hours a day I just saved to work on my motorcycle. It's much cheaper than paying someone else to do it.
