Lower fees: If you take an active trading approach to investing, then it is expected that fees from exchanges will trim your profits. With a long-term investment strategy, all the investor has to do is select a few cryptocurrencies, and then wait. A long-term investor does not trade every day, therefore, they do not have to worry about trading fees.
Some bitcoin exchanges allow account holders to short — bet that bitcoin will fall in value — but the ordinary investor cannot do this as easily with bitcoin as with stocks or exchange-traded funds. Shorting is easy on the futures markets, however, as the trader simply buys a contract to sell a block of bitcoin at today's price sometime in the future. If it works out the price will fall and the bet will pay the difference.
Please note that virtual currency is a digital representation of value that functions as a medium of exchange, a unit of account, or a store of value, but it does not have legal tender status. Virtual currencies are sometimes exchanged for U.S. dollars or other currencies around the world, but they are not currently backed nor supported by any government or central bank. Their value is completely derived by market forces of supply and demand, and they are more volatile than traditional fiat currencies. Profits and losses related to this volatility are amplified in margined futures contracts.
