No, Kickstarter backers don’t make money, because it’s rewards-based crowdfunding. That means backers get rewards (such as products) for donating instead of cash. Other crowdfunding types do let backers make money, though. For example, some venture capital companies use equity crowdfunding (which gets you partial ownership of a company) to find their next investments. Likewise, accredited investors sometimes use debt crowdfunding (which can earn your interest on your investment) to get a monetary return.
