1. where website trusted for buying paypal with altcoin?
2. Small fee?
As it was stated here, use the currency exchange site to transact if you're trying to get back fiat. You won't really be paying fees as you might have if you were on an exchange. Your other option is to convert your altcoins over to ethereum or bitcoin, as those are more common currencies for people to buy. You could sell on sites like localbitcoins, but I think ideally, you should stick to these forums. When transacting, make sure you use an escrow to ensure a safe deal!
