You may also wish to explore other forms of Bitcoin margin trading, whereby you buy or sell. When you place a buy order, you anticipate that the Bitcoin price will rise. Once they do, you will sell them to close your position, and therefore make a profit. When you place a sell order, you anticipate the Bitcoin price will drop. When it does, you buy back the Bitcoins and the difference is your profit. Your broker lends you the Bitcoins to trade with, hence the term margin trading.
