The worth of every airdrop is depends on the project, if they succeed well the token that they've giveaway may have a good price, but the reality is, many of these airdrops become worthless because many of the coin/token doesn't survive on the high market competition. In your question if it is worth, yes but I would suggest that you choose airdrops and bounty that are base on BSC because just incase you receive your reward you can easily transfer it in exchange your coin are supported with a low cost of transaction fee.
