99% of people who bought into bitcoin can make money out of it only if the cryptocurrency is on the rise. In order to make money when it declines, one might consider bitcoin futures contracts. Unfortunately, futures listed on exchanges such as CBOE and CME are unavailable for an average bitcoin holder because of their high price. The contract size on CBOE equals one bitcoin, while CME requires five bitcoins. That being said, one would need to make a minimum deposit of $10,000 to trade on these exchanges. But there are still options for small traders.
