Supply and demand, for sure. And these days, the demand has been lessen by the act of banning all exchanges and trading platforms in China, which by far, has affected the price of bitcoin. There are, or maybe i should say there were, thousands of people trading bitcoin and many other alt coins from China, and if you take them out, which is what has been done recently, then it is what we see; affected marketplace. For bitcoin to keep going higher, it needs the demand to increase, but if the demand goes in the negative way, then of course we will see a drastic change in the price.
