Bitcoin touches the price of 19,000 USD in December 2017. After that the price drops to 6,000 USD. Conditions like this now complicate bitcoin trading, as if the market is waiting. The person who will buy is doubtful, worried that the price will go down again. Likewise sellers, hoping prices will rise again. The market is waiting for momentum to bounce back, for example, interesting news about bitcoin, or the stock market in a large country that provides more space for bitcoin.
