Airdrops are still worth it, especially with the bull run coming. Projects that have been thought to be dead are starting to gain traction and new projects giving out semming low value tokens could be worth something significant in the near future. However, many of them are not encouraging, offering little to no value in the immediate /short term.
I wouldn't disagree with you on this because many projects that was fond dead some are coming back to get the needed traction from potential investors and when this happen the airdrops will be a good boost for the time used. Am also saying, the type of the airdrops matters alot. Some are still worthy of doing while some are just for the wasting of participants efforts, so, before embarking on any airdrops, ensure to verify the projects and the token real world case use.
