Is there a payment processing service available that accepts all popular payment methods?
Answer by Roger Gu:
At this point you will likely need two. PayPal can handle PayPal and all major credit/debit cards. For Bitcoin, will need a separate gateway service such as BitPay, CoinBase, and eventually, Circle. David Marcus, president of PayPal has indicated while he likes the concept of Bitcoins, it is too immature right now to be considered for inclusion in the PayPal gateway..
