cutesakura/aronnov,
Precisely, that is how pretty much any market works (buy/sell to price interaction) and without regulation like you said, well, this is what we get. A random price action and high volatility.
But regulation (centralization) is what we really want to avoid with Bitcoin. Right?
Although some kind of regulation exists within the Bitcoin universe. Satoshi, the Winklevoss brothers, among others, hold huge bags of coins. Any of them decide to drop their bags and we will see the market collapse. Why aren't they selling? Because they may be all together in this. So a small group that holds the majority of the goods is basically a controlled environment.
Trying to figure out the above is beyond any of us, we can only provide our thoughts and ideas. Which is also good, makes us smarter.
Ultimately, what I am trying to prove here is that Bitcoin does follow some of the rules of the trading market. The reason? Well, because it is traded.
