Bitcoin is designed to be cornered. There are just so many of them, and someone with enough fiat can buy as much of it as he or she wants, driving up the price, then dribble it back into the market like a central bank maintaining its price. Decentralized? Right, until a latter-day J.P. Morgan "centralizes" it.
Right now, HODLers are together "cornering" the market by buying and not selling. The float shrinks as the supply grows. No wonder the price is rising.
Absent government intervention, which is becoming increasingly likely, there is no reason why the price would not continue to rise, as there is no self-regulating, arbitrage-based equilibrator in the market. That's because no one actually uses BTC as money. And that's because BTC isn't money; it's a payment method, which means that its value does not matter so long as that value persists long enough to buy it, send it, and sell it.
