This happens all the time. Why should I be surprised or angry?
That is for you, because you can't be expected to some people there especially newbie to crypto currency.
They will be interested to follow every information given by hackers until they fall to the trap.
At least if we try to always give attention and caution the newbies will know that is a hacking/scam attempt and they can avoid it for sure.
Users who always want to take the short cut, those who always want to double their profit or coin within a short time or those wanting to hear anything sweet or things too good, they always fall for such scam or hack because if you sign up to a scam platform, your data has been exposed already.
