Escrow does not make you safe, if you just use the escrow for the initial deal (you send paypal we send btc)
If you want to be truly safe, you must escrow for the full 120 days it takes for chargeback to not be avaliable, then you release funds, but this is too long of a time to be worthwhile.
I wouldn't trust Newbie and Paypal in the same post.
180 days. If funded through certain credit cards, it's actually longer.
True, you can chargeback through the credit card as well if paypal wont do it for you.
Half a year escrow for 0.07 btc, forget it.
