I don’t think even 1 person falls for this but if they do, pray for their soul man.
I guess there are a few people stupid enough to make this worth their time, otherwise they wouldn't do it. It is simply a numbers game. Send the email to a million+ BTC-e users and you are bound to find someone stupid enough.
Older people that are computer illiterate may be more likely to open the file. Which reminds me... I need to inform my mom about this. She has some funds on BTC-e. I've tried for years to get her to move her BTC and LTC to cold wallets, but she doesn't seem too worried... I think older people have too much trust in the goodness of people's intentions.
