I saw the YFI fake airdrops on telegram and laughed so hard. How will someone in his/her widest dream believe they can get 0.1 YFI from airdrop, lol. I don't pity people who fall for such if it turns out to be a waste of time or scam. We should apply common sense before venturing any airdrop.
I saw this one too and many fall on this one, I hope they are still safe right now and their information is still safe, well I doubt on this.
There's a lot of scam promotions out there and they are taking advantage the peak of many DeFi projects, so if you see a good to be true offer you must think twice before giving up your information. Deal only with the real developer and know the risk of joining such a ponzi telegram group, don't make investing too hard for you, it easy to find a legit information about the specific project, do your homework.
