Everything was looking legitimate. This message was looking exactly the same as any other notification on fbc site. Same fonts, same colors, etc.
Now everything works as usual, so I guess I will never know what happened.
It doesn't look legitimate when you see such a message and someone asks you to contact them on their protonmail email. I know that Protonmail is used for privacy purposes but no company should write you or contact you with Proton email because they are LTD, they have responsibilities and they shouldn't be the one protecting their privacy on that level. Company should be public, open and should be using their own email servers instead of Proton.
So, asking for deposit and contacting on telegram or protonmail was already a red flag.
By the way, I don't understand what happened exactly, was that problem on your router? Or were all of your computers infected? Or was it actually the problem from Freebitco's side?
Ok, so since you actually asked, I will start a new topic about it and try to explain whole situation again.
I also think that it's not the right place to continue this story.
If somebody is interested with it and have any questions you can always ask me there.
Just give me some time to gather some things and describe whole story from the beginning.
Like I said before, I have registered account here mainly to show what I faced.
Fortunately, I was not fooled, but the matter looked serious.
