if you can find a local buyer/seller deal with cash only. I know that may not be possible, but credit cards will ALWAYS be riddled with high fees and low limits because there is a huge risk for a merchant with chargeback fraud from you. I don't think its even possible to buy with a CC short of coinbase and even they still need AML and will verify your bank statment.
Some europeans accept CC, I used to buy at BTC-24, they accepted LiqPay
BTC-E accepts several processors that accept credit cards...
Also Virwox accepts Paypal
And I cannot use Coinbase, like I said I am not from US, I don't even know what is a AML and I don't have bank account in US, or one where I think it is safe to send them my statment.
