Skyfchain IS asking for Private Keys. Any idea if this is legit? I must confess it does make me nervous. This is directly from the Skyfchain bot:
SKYFT Airdrop
Please, enter the private key of your Ethereum wallet 0x3b1048f776aAc71102C75404AeE46A242d817855 in order to automatically sign the special encrypted message that will verify that it is actually your wallet (We will not send SKYFT Token to fake wallets).
Enter Your Private Key: (hexadecimal character)
make it a golden rule not to share private key with any project , private key are only meant for personal use of user to login with official and genuine wallets . even login on exchanges with private key is considered harmful . so always use metamask instead of copy paste of private key everytime .
in metmask import the same private key for once and thats all .
I don't think any project need private key for airdrop . if really project asking such things then it is scam or in rare case project team noob in crypto market .
