hi i just got the following mail. but i have no idea what to do. please help.
Your are required to sign and verify 0xdf72250940e7528717f982beecabf05b6993f5853 Click the link below to sign a message from your address. Enter the Encrypted message you get afterwards.
This sounds very suspicious, and I would be very careful of a phishing attempt here. You should never enter private keys/usernames and passwords/login details/etc on links that have been sent or emailed to you. Always navigate your own way to MEW/exchanges/online wallets/etc. Safest practice is to bookmark the real and trusted sites.
