You are wrong, in many cases the customer has no recourse for credit card fraud: https://news.ycombinator.com/item?id=8918865 People think credit card anti-fraud measures are perfect. They are not.

It is very rare for people in countries where cards have PINs to both lose a card and give away the PIN to the thief. Banks have educated customers well enough to not write the PIN on the card. Likewise, a PIN-protected Bitcoin hardware wal

> The consumer isn't responsible for Credit Card fraud Wrong. In many cases he is responsible. Scenario #1: 60 days (typically) after the transaction, the customer has no recourse to report fraud. You were browsing your credit card

Which is easier: securing only 1 hardware wallet, or securing the HUNDREDS or THOUSANDS of merchant systems that your credit card information flows through?

Doesn't matter what the cause is. A 20%+ variance in mere minutes _is_ volatility, by definition.

In my scenario, a machine knows the local exchange price as of 0ms ago (instantaneously) but knows the remote exchange's price as of 5ms ago. You are saying it is better to know exchange A's price as of 2.5ms ago, and exchange B&#

No. The parent suggests having 2 machines (1 at each end), but each trading order would be issued by only 1 machine (not 2). So there is no synchronization issue. Example: machine A instantaneously become aware of some event at exchange A.

A very important issue with Key Vault is: what to do when the Hardware Security Module dies? All electronics fail or stop working at some point. How do you make backups of keys that were on the HSM?

I disagree. City driving at 25 mph is a lot more complicated and needs a lot more computing power than highway driving at 60-70 mph. City driving involves: handling the "dead zone" of intersection (square of pavement with no marki

> A small number of major bitcoin holders mostly determine the price. Wrong. Your assertion is easy to debunk: if this was true, then, since they hold many bitcoins, why don't they make the price go up to increase the value of thei

That's a misleading comment. Sure, if you bought BTC on January 1st, 2014, maybe, since this would have been timed perfectly to align with the peak of the Bitcoin bubble. But if you bought BTC only 60 days earlier (November 1st, 2013),

And credit cards provides zero protection against identity theft. In fact, they even enable it because you give your full billing info (credit card number, address, etc) when paying an online merchant with a card. You see, no payment techno

You are incorrect. An HTTP GET still requires a 3-way TCP handshake, so your suggestion requires 5 steps not 2: 1. TCP SYN to port 80 2. TCP SYN/ACK 3. TCP ACK 4. HTTP GET 5. HTTP reply with HTML content

That's because the author made a calculation mistake. He wrote "412" instead of "414".

Sell on an exchange. The big ones have a monthly trade volume of 100k+ BTC ($50+ million): http://bitcoinity.org/markets/list?currency=ALL&span=30d Clearly $200k is a drop in the bucket for them.

I strongly disagree. Bitcoin is an improvement for 2 reasons. 1. Fraud come most often from customers (who have nothing to lose), not from merchants (who need to maintain their reputation). As a matter of fact, fraudulent chargebacks cost m
