I'm not fan of any expert analysis and stuff because these so called experts will make money of you sooner or later, you can still use them to stay up-to-date with stuff but do not blindly follow them.
There are lot of airdrop experts found on Twitter/Telegram and they all try to make money of their audience once their userbase is grown enough.
I'm also in many groups that analyze new projects and airdrops. These analysts have a lot of experience since 2017, and their fundamental analyses are followed by a large community. Of course, they benefit from these activities: promoting projects, getting referrals from hunters, and receiving additional tokens from the projects.
I know that the market is full of scammers, but not everyone who shares information for free is a scammer. They have large communities, they benefit from those communities, and they will need to protect their reputation to continue to exist and earn more income from the value they create and give to the community.
