Even if you send the money as a gift, you can still force a chargeback (up to 30 days later) by claiming that your account was hacked. Even if Paypal refuse to issue the chargeback (which they wouldn't) you could have your bank issue the chargeback instead. I'm sure there is someone out there that will take a chance on you, but i doubt they'll do it for a few thousand dollars worth.

Technically, even bank wires and SEPA transfers can be reversed, but it's still the safest way.

I think a bank wire is safe after 36 hours, and a SEPA transfer is safe after 3 days.
