So there is no risk in shipping because you are 100% positive that you have the money you expect you have.

Only if you wait for a significant amount of time (days?) to verify the transaction. If you use a payment processor and they allow you to pass through transactions without verification, they are assuming that risk for you, but the risk is still there, and there is of course also risk caused by the currency volatility, chance of theft or loss of coins (very different from digital cash, more like paper cash), etc.

I'd be interested to know how companies like bitpay hedge that risk, or the risks caused by Bitcoin volatility, if indeed they do.




> Only if you wait for a significant amount of time (days?) to verify the transaction.

What? Two or three confirmations are generally irreversible. Six - an hour, give or take - has been generally agreed to be absolutely irreversible since the original Bitcoin client (if it's not, there's something really wrong and Bitcoin isn't as valuable as we thought).

If you're using a payment processor which takes risk that doesn't need to be there because you're not going to have your items in the post in an hour anyway (i.e. the vast majority of merchants), you're simply wasting money.


Credit cards generally verify in seconds, so this is a significant difference, even if the time is hours (I'd read somewhere it could be days for 7 confirmations, but thanks for the correction if that is never true and it is hours) - that confirmation time varies wildly and is not predictable is also an issue. A lot of merchants ship almost immediately after orders are completed (e.g. digital goods), so introducing another delay is not great and a significant downside for both merchants and consumers.

These and other technical challenges like blockchain size are probably soluble though, esp. if it hit scale and people were working on it, what worries me more in terms of mass adoption is the attitude to other risks like security, volatility and lack of insurance in the Bitcoin community, the insane requirements for sending in copies of passports etc that exchanges still have for purchasing bitcoins, and the fundamental problems caused by giving individual cryptographic keys perpetual value.

It would certainly be nice to have a payment system not controlled by Visa/Mastercard, and I imagine one is coming, but I'm not convinced Bitcoin is that alternative because of the assumptions baked into its design that we need to exchange tokens in order to exchange value.


> the insane requirements for sending in copies of passports etc that exchanges still have for purchasing bitcoins.

If you've ever bought foreign currency in a bureau de change, you'll have had to provide ID. It's the same set of laws which require Bitcoin exchanges to require ID. Take it up with your Government.

Which is equivalent to a 0 confirmation transaction, so no it's not a difference. Cards can be reversed for months, that's what 6 confirmations is competing with.

The CC issuer is queried for the card status, funds available, address etc, and transactions are accepted or declined based on that information. Sometimes there's even an extra verification step directly contacting the issuers bank to check a passcode (SecureCode), and all that is reversible afterward if a mistake or fraud is detected.

In what way is that analogous to a 0 confirmation irreversible bitcoin transaction?


Safety for the merchant. First off, funds don't need to be checked, there is not a card status or funds available, address is not necessary so all of those things are problems cards have that Bitcoin doesn't; they aren't relevant.

It is just as safe to accept a 0 confirmation transaction as it is to accept a credit card. In both cases, the transaction could be essentially reversed either by a double spend or by a charge-back. And frankly, a charge-back is far more likely than a double spend.

In both cases, the merchant is equally out. Bitcoin typically clears in less than an hour while cards don't clear for months. There is far more risk of a charge-back in months than there is of a double spend in the milliseconds it'd have to occur to be successful.

Cards offer more safety to the consumer of a fraudulent vendor of course, but that's the nature of cash and that's when you use escrow if it's big enough to worry you. However, fraudulent customers are far more common than fraudulent vendors; it's the vendors who need the most protection here and it's the vendors the current system disfavors.


If it's 0 confirmation, what exactly is checked?

I'm not convinced vendors are the important party here, they are making a sale and the onus is on them to provide an easy method of payment. Convincing customers to give up the protections of CCs or other digital cash payments would be a very hard battle. Escrow is not a viable alternative to verified identities in transactions, and for most consumers the slim advantages of Bitcoin are far outweighed by the numerous disadvantages.


> If it's 0 confirmation, what exactly is checked?

That's it's been broadcast to the network.

> Convincing customers to give up the protections of CCs or other digital cash payments would be a very hard battle.

No it won't, customers don't like sharing their credit card information online, it's why Paypal is still in business.

> and for most consumers the slim advantages of Bitcoin are far outweighed by the numerous disadvantages.

Not when they trust their vendors. I trust Amazon for example, I don't need to pay a few extra percent to the card company for consumer protection. Bad reviews work far better in getting a vendor to act.


>> No it won't, customers don't like sharing their credit card information online, it's why Paypal is still in business.

Paypal is in business because it's easy, nothing to do with giving out CC details.

>> Not when they trust their vendors. I trust Amazon for example, I don't need to pay a few extra percent to the card company for consumer protection.

Then you'll end up paying a few percent to amazon to protect you from vendors in their marketplace. Comes down to the same thing.

>> Bad reviews work far better in getting a vendor to act.

Typical libertarian nonsense. It doesn't matter if I get ripped off, I'll leave a bad review! We don't need health regulations for restaurants, if I get food poisoning and die I'll just never eat there gain!

Reality does not work that way, and we have all of recorded history to prove it.


Libertarian nonsense huh, despite what I said being completely true on amazon, and me not being a libertarian but a bleeding heart liberal, I'm just going to say you're trolling for a political argument with such idiotic abandon that I'm not wasting another breath on you. Go troll reddit.


I'm sorry you feel it's trolling, I'm not making a political point, and it's not how amazon works now, amazon are a broker in trust and take their cut, just like the companies you object to.


>> Safety for the merchant.

Sorry, but f*ck the merchant. We have thousands of years of history of consumers being ripped off by merchants. Laws and payment methods have spent the last few decades arranging themselves on the consumer's side and you want to rebalance evrything in favour of the people who have (historically and continually) been ripping the rest of us off?

No thanks.


This insurance is not free. I want the option of saving the 3% interchange when I'm dealing with a merchant I trust, like Amazon.com for example.


Merchants are ripped off by consumers far more then consumers are ripped off by merchants. That's reflected in the prices of goods which means the consumers are still being fucked by it. Saying fuck the merchant is profoundly ignorant; it's always the consumer who is fucked in the end.

As it should be.

Not anywhere near as much as they get screwed withot it.

>> Saying fuck the merchant is profoundly ignorant; it's always the consumer who is fucked in the end.

Disagree.


I think you're drastically overstating the risk of a double spend.


Maybe so, I did mention other risks though.
