To be honest, one can earn a lot through Airdrop Campaign or even Bounty, but it just needs to be a quality option.
In my opinion, it is better to do the bounty program because it gets more results.
I wouldn't choose the untrustworthy option either. With the Airdrop Campaign, you won't be able to do anything like that. Because doing so will only make things more difficult.
I am personally always cautious and that is why I only participate in Campaigns that are absolutely trustworthy and can be relied on to work on.
And what about NFT drops, like the one from MAXX Finance? Has anyone had luck with NFT drops?
I think with NFT it is even worse situation then with bounties or airdrops. When you get altcoins, at least they had sort of a use case in a project, at least they are needed for something. Which gives them some chances to be on demand. With NFTs, they are practically useless. To make them worth something, you need someone that is ready to buy them. Holding them usually gives you nothing. And you cant easily sell them. You can only create a sell order for them, when there are not buy orders, means you will have to wait for a customer.
