> But the point here is that crypto can enable a whole lot of other businesses that don't exist today because of merchant risk. This doesn't address the primary risk that merchants take on: fraud. Either crypto or credit card, if you end up taking a payment via stolen credentials, you will refund the money. The risk that the middleman in a two-sided takes on is fraud. The scam is pretty simple: steal credit card/crypto key, set up fake seller account, buy stuff from yourself using stolen credit card/crypto key, cash out. The middleman pays the money out to the scammer, and eventually has to pay back the person that was stolen from, credit card or no. Micro transactions are a huge merchant risk not because angry customers can chargeback, but because one stolen account can undo 1000/X legitimate transaction (where X is your profit per transaction). If your margin is slim, you've just amplified your fraud risk. And before you say that it's easier to steal credit cards than crypto keys: 1) wait until crypto becomes common and 2) it doesn't matter. If you secure your keys, then scammer finds some user's account credentials and cleans their account out.

> Either crypto or credit card, if you end up taking a payment via stolen credentials, you will refund the money. This by itself shows that you are making a fundamental confusion: crypto is not to be compared with credit cards. crypto is meant to be cash. Anyone that steals crypto will wash it before attempting to spend it. And depending on the network, you can't even know what is the origin. So, it would be the same as being robbed of cash. But okay, let's move on. > If your margin is slim, you've just amplified your fraud risk. What if my margin is infinite? Say I want to sell digital goods, with an effective unit cost of zero. Why would I want to worry about the 1/1000 chance of someone "stealing" a copy, when that cost is nothing compared with credit card processor fees and the only thing I am trying to avoid is being hit with chargeback fees? > wait until crypto becomes common Crypto becoming common does not mean that people should be keeping large amounts in their wallets. A wallet is not a bank account. Even those crazy enough to keep substantial amounts of funds in crypto would have (at least) two separate set of keys. One to use for their "hot wallet" and one for cold storage. This is almost basic practice. In a world where crypto "becomes common", what could happen is that your "bank" would be a service that is responsible (and properly paid) to be a trusted custodian of larger funds.
