BitCoins, Money, and Winning the Currency “Game”

I got linked to an essay by Jon Callas in which he talks about something that he claims is an amazing property of BitCoins:
Did you know that if a Bitcoin is destroyed, then the value of all the other Bitcoins goes up slightly? That’s incredible.
Now there are many properties of BitCoins that actually are incredible. The distributed generation and book-keeping system is awesome, as is the cryptographic trickery underpinning the coins themselves. On a more abstract notion, the whole idea of a pure-virtual currency is itself pretty incredible, seeing as how it seems at first intuitively impossible to satisfy the requirements of finitude and transferrability required for a medium to actually be a currency.1
But this deflationary property that Callas calls out isn’t one of BitCoin’s incredible properties. In fact it isn’t incredible at all. It’s a simple and obvious result of the fact that BitCoins are a currency. The fact that destroying a unit of currency causes deflation holds true no matter what currency you’re talking about. If I were to melt down the change in my change jar here in my desk, the value of all other American currency would rise slightly. Very very slightly. Imperceptibly so, in fact, but it would rise.2
There are a few questions around the destruction of physical currency versus BitCoins3, but Callas doesn’t actually address any of them. Rather he inducts from his observation that destroying a BitCoin causes a very small amount of deflation and proposes that there’s are a few dominant strategies to maximize the value of your BitCoins (a pursuit he gives the excellent title of “the BitCoin Game”.)
His three dominant strategies:
(1) Create more Bitcoins.
(2) Buy up more Bitcoins, with the end state of that strategy being that you’ve cornered the market.
(3) Destroy other people’s Bitcoins. The end state of that is also that you’ve cornered the market.
I submit that none of these will actually accomplish the state goal of the BitCoin game of “maximizing the value of your BitCoins”.
Wither regards to point 1, if you create more BitCoins, this will have the opposite effect that Callas (rightly) identified with destroying them. To whit, each coin you create will very slightly decrease the value of all the other BitCoins in existence, including your own. Now if you were the only person creating BitCoins, then there’s a chance that your total value of coins would increase fast enough to outpace BitCoin inflation, but since BitCoins are a distributed currency which anyone can work at creating, this seems unlikely. The much more likely scenario (and the one baked into the design of the currency) is that many people will create more BitCoins, thus distributing the effects of inflation fairly evenly. The sinking ship of BitCoin value will sink with an even keel and everyone will lose out in balanced measure.
As for 2 and 3, I’ll lump these together, both because Callas did and because Callas correctly understood that they have the same end result. Whether you buy up all the BitCoins or destroy everyone else’s BitCoins, you end up with all of them and they end up with none. Callas identifies this state with “winning the BitCoin game” and asserts that this would turn a distributed currency into a centralized currency. He’s incorrect on both counts.
First of all, if one person monopolized all BitCoins leaving everyone else with none while also destroying or buying at very low prices the coins produced by other people, then the value of BitCoins would very quickly drop to zero. The deflationary effect of destroying currency is not monotonic, and hoarding a currency that no one else values doesn’t make you rich.
You see, the fatal mistake that Callas his made is that he’s treating value as objective, when in fact all value is subjective. If I were to destroy all other US Dollars in the world except for the contents of my change jar, I wouldn’t have maximized the value of my currency. There’s probably $100 worth of coinage in there now, but if all other US currency was destroyed, then when I went to spend it, I’d have a hard time getting anyone to accept it. I’d probably find that people had stopped using dollars in favor of something more available (read: usable) and hence, more valuable. I wouldn’t have maximized the value of my currency, I would have destroyed it.
This is also why Callas’ second conclusion is incorrect. If BitCoins got “centralized” in the sense that one person horded all of them, then BitCoins wouldn’t become a centralized currency, rather they’d stop being a currency altogether. Currency, after all, is nothing but a token for deferred barter. In order for a medium to fill that role, it needs to have several properties including the ability to be transferred (circulate) and it needs to be trusted. A world in which one person destroyed any BitCoin they didn’t control would be one in which no one would trust BitCoins and so no one would use them. BitCoins would cease to be a currency altogether. Similarly, if that person just horded all the BitCoins and never used them for anything, BitCoins would be permanently unavailable and so people would abandon it in favor of other currencies that actually, you know, worked as currencies.
1 – For more on this, cf. this post.
2 – In a bizarre paradox of inefficiencies, it’s also possible that, if my change jar were to contain enough pennies and nickels, I might be able to also increase my own net worth, since the resulting plug of slag might be worth more than the face value of the coins that when into it. For more on this, cf. this video of author John Green getting hilariously worked up.
3 – E.g. the metaphysical question of what it means to “destroy” a BitCoin, since such coins are actually numerical constructs and, hence, numinal and indestructible. Of course a practical form of destruction would just be that BitCoin and all traces of it being deleted from all the computational media in the world.
