I think that is a scam. Maybe their motive is to know if the email their sending has bitcoin in coinbase so they can hack it. My advise is don't bother to enter any information to them even to log in with their links.
Hi everyone it seems that i have a little knowledge of bitcoins transactions based on what i've read above. What is a cold storage? What is encrypting? Do we have a thread here where I can read all of this stuff. Sorry Newbie here and new in btc either. Thanks for helping in advance.
