this is the message :
check the e-mail address .
I have clicked the link and inserted my password , but after I while I checked the e-mail who sends the message and compared it with old message from poloniex , they are different , so I recognized that it is hacking attempt , and fast , logged in my poloneix account using google search ( for more ensurance ) and changed the password . I hope I am safe now because they have the old password .
please be careful because there are a lot of hacking attempts as Bitcoin price is increasing .
To verify it is a real email, please look at the RAW html code of the email and read all the text. Once u see that the host is not the real poloniex mail, then u know it is fake and that u should report it as spam and block that email address. Don't fall for phising sites.
