Are there any websites in which I can buy altcoins using Paypal?
As I know directly is not possible ( Paypal policy) you can use Virvox.com to buy bitcoins ( altcoin is not possible) Paypal deposit-fiat to linden dollars- linden dollars to btc (PS: Virvox fees are exorbitantly ) then you can withdraw your btc and exchange them for altcoin. The only good thing is that everything is fast/instant etc...
