How to get free airdrops?

Could you please elaborate on the process of obtaining free airdrops? I'm particularly interested in understanding the steps involved, any prerequisites that may be required, and any potential risks or considerations that I should be aware of. Is it necessary to hold a certain amount of a particular cryptocurrency to qualify for these airdrops? And how do I ensure that I don't miss out on any of these opportunities? I'd appreciate any insights or advice you can provide on this topic.
