How to identify scam? In some cases it is difficult, in some it is even impossible so they become smarter and smarter.Personally, I try to identify projects by their website - how it is made, how much information is there, what kind of information, how well and how long the team worked on it, in how many social networks they are represented, if everyone works. I look with particular caution at projects "based on DeFi" or "yearn", which in fact describe the general provisions and principles of work of my project. I also immediately discard such projects where in telegram groups they obsessively throw info a hundred times a day buy tokens buy, immediately it is clear that no one needs such tokens. And about airdrops, there are generally a lot of scams, just send 0.03 eth to get an airdrop worth something)))
