Invest in futures on an open source market
Visit Bugmark to find an open issue that matches your skills and interests. Buy a futures contract connected to that issue that will pay you when the issue is fixed. Work on the issue, in the open, then decide if you want to hold your contract until maturity, or sell it at a profit.
Create a new issue or select an existing one. Buy a futures contract that will cost you a pre-determined amount when the issue is fixed, or compensate you if the issue goes unfixed. Reduce your exposure to software risks by directly signaling the project participants about what issues are important to you.
Development isn't the only task required to make a software project a success. You can trade futures to earn a profit from other vital tasks, such as clarifying and translating bug reports, triageing bugs, writing failing tests, or doing code reviews.
