  1. Re:A limited number of Bitcoins on Bitcoin Thefts Surge, DDoS Hackers Take Millions · · Score: 4, Informative

    The effect of selling is less than you think.
    mtgox is not the biggest exchange, but it can easily do a $1M exchange without affecting price in a too dramatic way.

    The nice thing is that their bid book is open for every one to see, so you can predict what happens to price at large orders.
    See: http://mtgoxlive.com/orders
    At the time of writing, a $1M sell or buy would move the mtgox exchange price 5% in either direction.

    If you sell in the largest exchange in the world, which I understand is in China, it would move the market less than this.

  2. Re: Sell now. on Bitcoin Tops $1,000 For the First Time · · Score: 1

    If 10 people with 1000 bitcoins each now went to MtGoX and wanted to cash in their bitcoins, what would that do to MtGoX? I think they'd be fucked.

    Seriously, this is empty speculation and there isn't the actual money invested in bitcoins to support this increase in face value. The system is fucked. Theres no way the bitcoins in circulation today could actually be cashed in for actual money.

    Due to the open nature of the bid book at MtGox, you can see EXACTLY what happens at a sell of 10k btc.

    At the time of writing, it would drive down the price to $800,- roughly.

  3. Re:Is my reasoning sound? on Security Breach Forces Bitcoin Bank Inputs.io To Halt Operations · · Score: 1

    My line of reasoning is such: credit is necessary for the functioning of the modern world. A world dominated by Bitcoin will still have credit. Credit without regulation would be disastrous. Banks cannot be expected to self-regulate properly. A regulatory agency would be in charge. This regulatory agency would then have control over the amount of money in existence. And then we are right back to square one, in terms of the government's involvement in money.

    Good point.
    There does seem to be some catch22 here.

    Still: how did the economy of the 19th century work though?
    Bank notes were still linked to gold that was in the bank's vault.
    They seemed to make it work.
    As a matter of fact: US economy did extremely well in 1800s, where pretty much every year, there was deflation instead of inflation.
    Most years, you would get more for your dollar than previous year.
    Translate that to the hypothetical 2030 economy where the gold is replaced with bitcoins, would it not be able to function?

  5. Re:Is my reasoning sound? on Security Breach Forces Bitcoin Bank Inputs.io To Halt Operations · · Score: 1

    The 21M bitcoins are just the "base" money supply. I assume in this future world order we are not prohibiting the formation of banks or the ability to get credit. Once credit becomes available, and the issuing notes become "almost as good as" the bitcoins that back them, then the total amount of "money" in circulation may be much, much more than the 21M bitcoins and will probably mirror growth in the real economy.

    Inasmuch as credit is desireable and banks serve a purpose (and even a "central bank" may serve a purpose), you might see all of these institutions rise up naturally around this new currency, and the fixed 21M won't matter much at all.

    You make a good point, which I had not considered.
    Still, the 21M limit will still matter I think.
    It *used* to be that banks had a strict minimum reserve for deposits.
    Even with the 'money multiplier effect' the bitcoin will be a scarce resource for the banks, assuming that governments will still dictate a minimum deposit reserve. It's unlikely the minimum reserve will be scrapped altogether, as it would make banks too vulnerable.

  6. Re:Is my reasoning sound? on Security Breach Forces Bitcoin Bank Inputs.io To Halt Operations · · Score: 3, Informative

    The value of owning 1/21M of the entire money supply depends entirely on the price level of the goods and services you can buy with that money.

    Right now, someone might trade you an iPad for 1 bitcoin. Maybe in 2030 that bitcoin gets you a gallon of milk.

    That does not make sense: it would mean that the worlds money supply in 2030 would be enough for just 21M gallons of milk and nothing more.
    Bitcoins are set up for hyperdeflation, not inflation.

    Wikipedia calls this 'its deflationary bias'. (http://en.wikipedia.org/wiki/Bitcoin#Economics)

  7. Is my reasoning sound? on Security Breach Forces Bitcoin Bank Inputs.io To Halt Operations · · Score: 4, Interesting

    I've been analyzing bitcoin lately, and have come up with the following reasoning:

    As the coins are limited to 21M coins, you can, at this date, purchase 1/21Mth part of all the coins in the world for $300,-
    Even if you put the odds of bitcoin supplanting US dollar very slim (1:1000), the only rational choice is to buy bitcoin.
    If in 2030 the world uses bitcoins, you end up owning a sizeable portion (1/21M) of the entire money supply of the world's default currency.
    How is this not a good deal? Heck, even at 1:1000000 odds of bitcoin supplanting US dollar would still make sense at $300,- per coin.

    Where is fault in my logic? It seems too easy.
