Furthermore, I would be forced to use an intermediary financial institution such as a bank to hold my money for me, and thereby expose myself to yet another layer of required trust and accompanying risk. I would also be aware that these institutions would almost certainly practice fractional reserve banking to the maximum extent they could get away with it, such that they would be extremely fragile to small perturbations and vulnerable to things like bank runs and runaway systemic banking collapses.
 Market share: this can be defined as the proportion of market capitalization that a cryptocurrency has. A large market share typically indicates dominance. For example, Bitcoin’s market share is currently 60% (at the time of writing) of total market capitalization of the cryptocurrency space.

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.
