i won't use credit card, it's totally risky than using debit card or bitcoin, so much fraud i think,about debit card there are already bitcoin's debit card out there where you can deposite your card via bitcoin, but it took much cost when you cashout your bitcoin, but it's really help us to purchase something on store which they're not accepted bitcoin directly, so far i choose bitcoin, yup the simplest for paying things online
Yes, I agree with you, the credit card is really risky because each carders (A Hacker who stole a credit card) can easily to steal or scam on the web by going to the web are vulnerable, but the problem is that not all online stores can accept bitcoin
