I received an email (went to spam) detailing a password I had for an email account. In this email I was requested to purchase bitcoin to the value of $1900 (which this person thinks is a fair price for not sending the "alleged videos of me" to all my contacts on Facebook / messenger / email and of course, they will delete EVERYTHING once they get payment). I think differently, I'm worth WAY more than 1900 dollars (I assume US $), or maybe my contacts, who the videos will be sent to, would pay more than $1900 to NOT receive them 
Anyway, the password is a valid password but to a different email account (yahoo) - but none the less, I'm wondering how the beep, such made it from one email account to another and this request!
General advice welcomed please (no, I won't include you on the distribution list for the alleged video(s), if you do get any vids, then let me know, I'll start charging you!) - should this be reported officially to Gardaí? Should I use that old yahoo account again? Is my machine compromised?
I am VERY security aware in relation to any malware / software installs etc, but this is a bit more than just me getting a few million US Dollars off of someone in Nigeria who is trying to get out of their country and needs me to "hold their money" for them. I know Yahoo have been compromised in the past, and I did change my password after that on the account.
