It would be for now better to do with such messages.
You should read better what the OP has written, even if the hackers gets his password of his email they cannot do anything, as far as I am seeing here he already had setup 2FA before for both Yobit and his email account so I agree with OP hackers cannot do anything to him. The OP explicitly told us that he can open his email without 2FA only on his home PC which he claims is secure. I think he is safe so far but he can let us know further about his other accounts here.
You are absolutely right except the part I am not him but her but many persons here confuse me for a male and they don't believe much I am a girl, however what you are saying is totally right. All my other accounts are safe as they all have 2FA and I set up 2FA of a website I use only in my Linux machine at home. Locking this topic now as no more to say about this case I believe.
