With Bitcoin the user does not give out any sensitive creditcard information. Instead of giving out the information so the merchant can use this to withdraw money.
The user sends their money without giving out any information.
Thus there is no information for a hacker to steal or for an employee to abuse or sell.
This means that the network can have much lower fees. When you compare the fees a creditcard charges 100 000% percent higher fees per transaction than the Bitcoin network.
Another advantage is that its free to get a Bitcoin adress.
There is also a projekt in the work, that might make it possible to use a creditcard to pay with Bitcoins. Called Openpay.
So it might become possible to use Bitcoin at any shop that takes VISA/Mastercard.
But the real benefit is that the Bitcoins in a Bitcoin network only belongs to the owner controlling the adress.
As opposed to having the money in a bank, in which the money belongs to the bank.
What you see on your bank account is how much money you have lended out to the bank and for this they give you an interest rate.
Thus, Bitcoins is the only way to own your own money in electronic form.
1@NickODell you provided one of the reasons but not the only reason. Some transactions require a chargeback (i.e. escrow) system, because some merchants give bad service and don't issue refunds when they fail to honor their side of the contract or generally accepted business practices in lieu of an explicit contract. Note, there is a VerifiedByVisa program, where the CVV2 and/or password is never seen by the merchant. Security (as differentiated from privacy) may not be the strongest advantage for P2P currency over the long-term. – Shelby Moore III – 2013-03-21T17:00:42.937
1Hi George and welcome! You should change the title to something understandable that sums up your question. Is your question simply what benefits Bitcoin has over credit cards? – D.H. - bitcoin.se – 2012-08-18T18:58:35.770
The security model is different - with credit cards, you give private information to a merchant, and you need to trust that merchant to make charges correctly. Additionally, the private information that you give is exactly the same for all of them. This is why credit cards NEED a chargeback system. – Nick ODell – 2012-11-26T04:14:57.950
