Credit card companies almost unconditionally insure their customers against fraudulent transactions. Bitcoin does not. Banks will actively monitor accounts for suspicious transactions and lock the account if necessary. Bitcoin does not. Banks provide a friendly, easy to use and traceable list of your previous transactions. Bitcoin does not. Banks provide a mechanism to reverse transactions. Bitcoin does not.
Perhaps baddox meant Fraud protection for the vendor - chargebacks are impossible with Bitcoin, so once the vendor has the money/bitcoin, it's theirs.
As a consumer though, I much prefer the fraud protection that the credit card companies provide. And as a vendor, the 1% or less of chargebacks is probably outweighed by the number of customers who do buy because they feel safer using their credit card online.
Fraud protection in the sense that, if you protect your private key no one can steal your bitcoins. With credit cards you are constantly giving away your secret to third parties when you transact with them.
Bitcoin/cash shifts protection from third parties, like stores, to the user. This dramatically changes the nature of security in both good and bad ways.
Right, except it isn't a physical object like cash is, it can't be stolen from your person like cash can, and most people keep nearly all of their 'cash' in electronic accounts anyway.
It's not just theft protection though. Bitcoin provides protection from forms of fraud which specifically use mechanisms in a currency or transaction system, like chargebacks on PayPal (a ubiquitous form of fraud), or fake Western Union payments.
I prefer a user-securable account (like Bitcoin) over a laughably insecure account (like credit cards, where your "authentication" details are just a handful of numbers that you have to share with everyone you transact with) with a dispute resolution team.
If you know someones address then you can go back and check all the transactions.
As for refunds, merchants selling using bitcoin still have to follow law of the land, in most civilised countries there is a "Supply of Goods and Services Act" or equivalent legislation where a customer is entitled to a repair, replacement or refund if the good/service is bad.
Buying with bitcoin is no different to buying in cash
You obviously do not understand bitcoin or are confused about some aspects of it.
If you and I trust each other a great deal, we can do a transaction by exchanging a private key.
Groups of people that trust a third party can also do bitcoin denominated private transactions (the only visible transactions would be with the trusted third party). You see this at most bitcoin exchanges.
Credit card companies need to spend vast resources on fraud protection because their underlying protocol offers virtually none. Credit cards, after all, don't even have a basic "password." It's like the difference between an online bank account with no password but with a team of "fraud protectors," and a bank account with good two factor authentication. You can argue that both are forms of "fraud protection," but I vastly prefer the latter.
