There are still many airdrops that can make money, of course also with capital. As for the free ones, it seems like many are wortless.
but if we don't have time to do that, it's best to become a holder or trader, that can also make us profit in crypto
Trading, holding, bounty campaigns and airdrops are all good ways to generate income and profits, as long as the participants have enough experience, perseverance, and a little luck. There are airdrop hunters who have earned millions of $, or bounty hunters who have earned tens of thousands of $ through their enormous efforts, while many other traders and holders have not been able to do so. We have different time, budget, beliefs, and efforts, and we have different choices to succeed in this market.
Honestly, I would also like to participate in airdrops/bounties to earn thousands of $ for free, but I also don't have enough time to participate even though I know that these projects are really potential. I also choose trading and holding so that I can focus on more important work in life. After all, the crypto market is just a part of my life.
