First of all it's seasonal correction. Secondly it's Chinese and Korean holidays. Thirdly it's too huge capitalization and market just don't see yet how to keep increasing it even more.
It is true that we will have to be careful about price and demand for selling and buying. At time of low price it is good to hold and wait. Chinese are not in favor of bitcoin but now some of Koreans are also saying that bitcoin is ban for them in their country, it is not bad but to some extent it is because if all countries will love bitcoin and will support it will increase the bitcoin price and will make it world currency in very short time.
