I am not very active in participating in airdrop projects that appear on this forum or any other media channel. but when I opened Telegram I accidentally came across an airdrop DEFI (YFI) but it requires participants to send 0.005 ETH first. I think anyone who has joined the project or hasn't even had time to join in, should be even more alert. this is just a warning from me.
Anything that ask for money first i will threat it as a scam attempt. Not worth all to waste money on scam airdrop but if you have money to lose then you can try it out. Who knew it was a legit one.
