There is a lot of speculation about what will happen soon after BTC hits a symbolic milestone of $10,000. According to Cryptocurrency yesterday, "More than $900M worth of BTC were exchanged in the BTC/USD market, representing a 21.5% share of daily volume, second to the JPY at 60%".

A symbolic milestone on BTC reaching one million JPY occurred about 60 hours ago. Since then the price in JPY is up about 14% (11% in USD during the same time period). So, what does that tell us?
