At this time you can't do anything to increase or decrease the price of bitcoin . This is because at this time of the year many countries are renewing there budget so this budget making is one reason that the market goes down every year at this time. People are more concerned with whats happening in their country rather than with bitcoin at this time. Another reason can be due to the down fall in the stock market recently . This has affected the bitcoin so much that it decreases to 6200$ . So, at this time you can just buy more and more bitcoins and wait for some time as the price will eventually increase .
