Exactly. Ostracism is usually stronger than law anyway.

The grocery store needs good exchanges, even if you don't.

I was expecting a price drop at MtGox because of a loss of confidence due to the extended outage. To my surprise, MtGox re-opened with similar pricing to when it closed. I take that as a bullish indicator.

The policy could be to refund the price at which the product is currently selling. In your blender example, the refund would be 4 BTC.

That's a fantastic visualization. What is the left-hand axis? Time, I suppose, but it wouldn't hurt to label the axes.

There's no reason to consider trusting it. If it's a fake address, don't donate. If it's a genuine address, don't donate - because the address is sure to appear on the genuine website soon enough, and you can donate then.

"The Times" newspaper today claimed that approximately 2% of all the gold that has ever been mined is lost. That's less than I would have thought. Sorry, no link because I read the dead-tree version at the coffee shop.

Einstein's famous equation E=mc² describes the equivalence between energy and mass. Quantum physics is not involved.

If you push something so that it goes faster, the energy from your push increases the mass of the object by the amount indicated by E=mc². This is quite a small amount, so we don't notice it in day-to-day life, but it is readily measurable.

In the same way, a battery gets slightly heavier when you charge it up, and slightly lighter when you discharge it. This is due to the extra energy in the charged battery causing chemical changes that result in matter that has a higher energy state (and is therefore more massive according to E=mc²). Freaky, huh?

It was a joke, to help people to think about this laterally. As bitcoin2cash pointed out, there are economic advantages to mining at the generator.

Look at it this way: if there is a big bubble, lots of "ordinary people" will buy Bitcoins. If there is a price crash, they won't be able to sell their Bitcoins without making a loss, so they will use their coins to trade for stuff instead.

That's why I'm not concerned.

If electricity companies knew about Bitcoin, they'd use all their electricity mining for themselves, and wouldn't have any electricity left to sell to the public.

This is an awesome idea! I sent a small donation.

I would like to see the "winner takes all" option implemented. It would make a great way to resolve ongoing bickering: challenge everyone to "pay up or shut up".

And you will reduce the pay every week that the Bitcoin exchange rate rises

The accumulated market depth chart is already available on the MtGox megachart.

A three-dimentional "trench" (showing changes in the accumulated market depth over time) would be fascinating to see.

Additions are debits from a bank's point of view, but credits from a customer's point of view.

Then I didn't express myself very well. I wasn't expressing any concerns, just a prediction for the future.

Efficient and satisfactory trade with ph1223uk.

Ruby is delightful.

I have also transacted without using PGP, but the "Deposit Funds" page says that PGP is required and that will frighten away many potential users.

It's a pity he's not very interested in the service, because he has coded it up nicely.

The site asks for a PGP-encrypted email before you deposit Euros. That rules out 90% of potential customers.
