Gone are those days when someone would earn free crypto through an airdrop without doing anything. You can still earn free crypto now without basically investing your money into any crypto project, but you have to spend your time and data promoting a crypto project on different social media channels, and at the end of your promotion, you will earn free crypto for helping the crypto project gain awareness. One bad thing about promoting a crypto project on different social media channels to earn free crypto is that you are not guaranteed to be rewarded greatly for your hard work because most of the crypto projects that allow people to promote their project on different social media channels always end up listing their token on a centralized exchange with the price where their farmers will end up getting peanuts. If you have a steady income, it is better to use your money and invest in bitcoin because you are guaranteed you will not lose your money as long as you don't sell you bitcoin out of panic.
