You would hope that by the time 1 BTC = $10,000 USD the fluctuations or volatility in these 'early years' will have subsided. Otherwise, we could be seeing swings between $10,000 and $100,000 each month! The stress levels of BTC day-traders seem high enough as it is... what would happen then??
It would make it fail. Bitcoin can only work if it is stablilised.
