BTCTrader71, I don't suspect they would conspire to destroy the market, but there is a prisoners' dilemma type of issue. At what point IS it worth it to them because the rewards are so great? One could say they are relying on a "greater fool" theory. So far it's working. At some point, their calculus could change, and then what happens?
I'm familiar with prisoners' dilemma but I don't see how it applies in this case. I venture to guess that most early investors are strong believers in the technology behind bitcoin, and believe it is not a self-limited bubble -- otherwise, why invest in it? It would be too risky. They do not see bitcoin investors (or users) as a bunch of fools and do not envision some inevitable time when all the fools are going to jump ship. Bitcoin (or crypto in general) is a technology that has inherent uses that persist even if its value as a currency is zero. (There are a myriad of examples -- smart property, colored coins, voting systems, identification systems, proof of copyright, many more I have never even thought of). People pay money for other pieces of software because they are useful tools. Bitcoin is the same.
Suppose you owned 25% of all coins right now, personally. And suppose you were very persuasive and had the ears of the other ~1000 and together, you owned 50%. What conspiracy could you possibly dream up that would make you more money than HODLing some of your bitcoin, and growing the bitcoin ecosystem with the rest? That's exactly what a lot of the big investors are doing. (For the sake of argument, let's exclude from consideration buying an army and marching on everybody -- or buying a politician, which in my mind fits into the same category. IOW, let's exlude business as usual under the existing fiat system.)
Your reasoning is good, and I'm not trying to argue, but there are other possibilities.
They might be true believers. They might just be "rational actors" as they say in the case studies.
In a classic prisoner's dilemma, the "prisoners" (in this case, the 1000) could theoretically decide not to betray each other (in this case, sell BTC) for their mutual benefit. But as the rewards for "betraying" (in this case, selling) get greater, a prisoner might decide to pursue his own benefit.
Obviously, this is quick and dirty, but look at it this way:
12MM BTC at 650 means 7,800,000,000 in total value
50% of that is 3,900,000,000
divided by 1000 holders is 3,900,000 each in value held. Subtract out Satoshi's share and it's more like 3,575,000 for the other 999.
With 50% on the market, the selling pressure would be immense. I looked at a number of models analyzing float manipulation, order imbalance, and the impact on stock prices. If I read the models correctly, 50% of the shares on the market would likely cause MORE than a 50% drop in price, but even at a mere, say, 60% (and I think it would be higher),
So for the 999, with a price of 650, under price pressure from selling their shares, you're probably talking about maybe $1.4 million for each if they all cashed out now. That is IF the 999 are more or less together on this. And that's even assuming equal distribution among the 999, which isn't likely. For most of them, it is likely less.
So, you're absolutely correct when you say that their best move right now is HODLing their BTC and growing the total value...likely by growing the adoption rate and infrastructure. And keep in mind, if they are doing it because they are believers or because they are just waiting to cash out, it all looks the same to you and me. I mean, if it's worth $1.4 mil or maybe less to me now, that's pretty good, but I'm not ratting out my other prisoners. And no way would I even consider "voting" for a mass liquidation by the 999 if I'm one of them. I'm not sure I could even retire on that right now--damn sure couldn't if I'm in the bottom half of the 999. It might be close, but vuduchyld ain't tryin' to outlive his money.
What if BTC is $3250, though? Now I'm probably up over $5mm in a pressured market and $10mm in an unpressured market. Might be a little more pressure on some "prisoners" at that point. What about BTC at $10,000? Somewhere between $30mm and $60mm? That is getting close to buy-an-island money.
Again, I'm not saying they aren't true believers, but if they aren't, and if it's just the "greater fool" theory, this distribution could definitely impact BTC pricing. As long as they think there are greater fools to buy in at higher prices (obviously true right now), you continue to maximize value. But frankly, we've got people on this board who seem to think their 1 BTC is going to make them a dollar millionaire someday. If you are one of the 1000 who have an average of SIX THOUSAND BTC right now, would you settle for $1.4MM?
