Pretending he stole my password (in fact it is an old password that leaked on the internet and that I changed a long time ago) and taken some pictures of me while I was browsing porn to get money out of me

This is obviously the biggest nonsense, paying with Bitcoin is anonymous so the scammer cannot know who the money came from (there is no sender). The story as described in the mail is therefore incorrect and is not based on truths. MAIL says that he hacked my Mail account and he knows my pw if i will not pay 740 bitcoins hell post fotos and videos of me

I got a mail supposedly from my own self. The guy says he has hacked my system and took photos of me in various positions. He will make them public unless I give him $775 in bitcoins.

Received mail claiming all my contacts will be mailed compromising images of myself unless I pay $675 in Bitcoin to this address.
