someone on ebay wanted to but bitcoins from me. 4 for 400. He paid with a womans paypal account sending the payment as a gift. His personal email has a name completely different to the woman's pay pal. Is it a scam? I already sent 0.1 BTC then I started thinking... this is too good to be true.
Paypal is far from being secure, plenty of accounts are compromised on a regular basis, the cyber criminals then purchase irreversible goods (e.g. jewelry, Bitcoins) with the reversible goods (USD, Euro etc) using the compromised account.

BTC for 400$ isn't even such a good deal at the current rates.
Paypal accounts with balances ranging from 10,000$ to 100,000$ typically cost a couple hundred dollars for cyber criminals.
