The loss was realized yesterday, Aug 27, 2019 morning, I turned on computer, checked my e-mail as usual (again there was no notification from blockchain.com),
the transaction was made about the same time you're checking your email
but it gets confirmation almost an hour later, if you had acted fast you would have saved your coins
can you remember what emails you were reading/opening at that time?
did you open or click any link in your email?
did you check your blockchain.com wallet before or after reading your email?
