>People don't use credit cards because they are convenient, people use credit cards because they do not have the extra money

I use my credit cards because they don't cost me any more than using cash (I pay off the full amount each month) and I get a lot of various perks in return, like cashback, airmiles and insurance. They are convenient and I use them whenever I can.

Also decreased risk. Loose your cash and it's gone, loose your card and you just call in for another.

"People don't use credit cards because they are convenient, people use credit cards because they do not have the extra money, which drives compounded economic growth."

That's not true everywhere. I'm not sure if it's US-only behaviour, but in other countries, the majority don't use credit cards for debt - just as a convenient payment mechanism.

True, and fees are often way lower for debit cards as well. Not sure what it is in practice, but here's an example: http://www.cardfellow.com/blog/debit-card-charge-calculator-...

Sorry to pull an HN special on you, but do you have any kind of source for that? I've never heard it, though I have heard that debit card usage is much higher in Europe.

No reason to apologise for asking for a source :) Always legitimate.

Unfortunately, I don't have one. I do live in Israel though and I can tell you that here, at least, most credit cards are used like debit cards (as I understand them). We do technically buy on credit, but pay up at the end of every month.

We do have one thing which, afaik, doesn't exist in the US, which is that we can "split up" a payment when paying for an item. E.g. you buy something for 100$, you can ask to pay in 2 installments of $50. That's pretty common, and usually doesn't cost anything extra for small amounts of installments.

It’s very similar here in Argentina, but we usually have a different plastic piece to use as debit card and as credit card.

Well, with an N of 1, this is overwhelmingly how my wife and I use credit cards. Better consumer protection and less hassle than either cash or a debit card. Feel a little bit bad about making everyone else pay for that, but not bad enough to overwhelm those concerns.

What? I don't own a credit card, but I use a visa card all the time, because it's convenient. I'm pretty sure more people use their bank cards than their credit cards. It still the same crappy technology underneath.

There is no logical relation between credit vs debit cards, and fraud. You could have a bitcoin based account with a borrowing limit, which could only make payments to registered identities (equivalent of merchants), creating a credit card-like account.

And when you say that merchants find credit cards acceptable in spite of fraud, that doesn't imply that fraud isn't a huge drain on the economy, it just means that credit cards are still a better alternative than cash. But if we could get rid of the fraud, we would still save a huge amount.

Can you explain the scheme in which a user would be authenticated and authorized under a credit-card-like-account that would not be open to the kind of fraud we see on credit cards currently?

And you're right, what implies that fraud isn't a huge drain on the economy is that it comes from massively increased liquidity. Fraud is a biproduct of increased liquidity. I don't know how many times I have to scream this in this thread. If you aren't addressing the increased liquidity offered by cards you are missing a massive part of the equation.

Definitely a good point, particularly that bitcoin will have credit mechanisms built on top of it. Maybe I'm wrong, but I think that the point of bitcoin is that any credit mechanism built on top of it wouldn't have the same problems of identity fraud.

I also don't think the article is necessarily saying that we will have different crypto-currencies for each business, just that we already use a bunch of different payment methods (points, air miles, credit, etc.) and it will be faster and easier to choose which one you use.

How?

>If bitcoin succeeds, credit mechanisms will be built on top of it, and they'll behave almost identically to credit cards, including have fraud.

Why? One way transactions cut down fraud. It's not inconceivable to have a hardware digital currency wallet that can be used similar to the modern credit card. Banks could issue credit that is spendable in the same way with additional automatic escrow. Why continue to have the fraud ridden system when the alternative exists?

Huh? One way transactions cut down charge backs, they don't cut down fraud. It just moves the fraud risk to the consumer (and the wallets), instead of the merchants. Great for merchants, not great for consumers. Again, as merchants are already willing to take a cut to attract consumers via credit cards, it seems unlikely that consumers will be motivated to use bitcoin over credit cards.

Great point. As for the questions below, let's talk real numbers for the US in 2014:

Average household owes $7,115 on their credit cards. Average indebted household owes 15K+.

"people use credit cards because they do not have the extra money"

So you think it's better for people to be able to spend money that they don't have and pay usurious interest rates and fees, decreasing the utility of their future income and locking them into perpetual debt?

Maybe it would be better if credit were a bit more difficult to access so that people think about it more before utilizing it.

If you borrow against money that you're going to have before the next credit card bill is due, you're not paying usurious interest rates and fees. We don't always have the liquidity to pay for what we charge when we charge it but that's not at all the same thing as not being able to afford it (if we didn't have credit cards available, we'd shift our assets to otherwise be more liquid).

False dichotomy.
