Is there a thrid party site that gives protection when buying btc using paypal? I've checked Escrow but it seems according to their rules both buyer and the seller must be US residents and the transaction must be in USD. Is there any other sites similar that gives protection to non-US residents?
If you buy btc using paypal, you have no risk at all. Just make sure use escrow or send the paypal after receiving the btc. Paypal is available nearly all around the world. USD is commonly used currency in paypal. No matter which country you are from, you can receive USD, Euro, or many other supported currencies in you paypal balance. Paypal is reversible payment method, even with escrow, no matter you are us or non-us residents. Chargeback is for buyer protection adopted by paypal. Nowadays it has been misused by paypal senders. I don't think there is any sites which is able to give protections for btc and paypal trade.
