Remember that USA is about 5% of the world population, so I wouldn't expect holidays in one country to make too much difference in a global market. China might be a different story as they seem to be the main players.
I can easily see 10% gains in a year (if you smooth out the highs and lows). BTC'ers seem to be tolerant of higher risk than people for example, looking provide a reliable income from their life long savings put into BlueChips or something in their later years, than young guns who can afford a few mistakes when they are in their peak learning years.
For the next 10 years, the price rise will be bigger and volatility be higher. When the market cap reaches 1 trillion, the price will be stable.
