More importantly, we find that the ACP and ANET factors can price cryptocurrency returns. In particular, all of our five cryptocurrencies have positive and significant exposures to the fundamental factors. The explanatory power of ACP and ANET is over and above any effects related to the Bitcoin and momentum factors. This finding is non-trivial given that the five cryptocurrencies in our sample have consistently accounted for between 80% to 95% of the total cryptocurrency market capitalisation. Furthermore, we extend our factor analysis to an out-of-sample set of 33 cryptocurrencies obtained from the Bittrex exchange. We find that the aggregate computing power and network factors also price cryptocurrencies in this large out-of-sample data set.
This gives sellers an incentive to charge transaction fees, since they get paid faster by doing so, and so it’s fairly common for cryptocurrency transactions to come with fees.

The story of cryptocurrency scammer Dr Ruja Ignatova's London flat - and how her purchase was concealed.
The 2-year-old exchange, already the largest in the world by volume, revealed in June that it would stop serving U.S. customers on September 12 as it plans to formally enter the American market with a regulated fiat-to-crypto exchange.
Even after falling back from its latest all-time high price, Bitcoin’s current price still represents a big upswing from the low $40,000 range seen in September.
The liquidity pool of a crypto exchange is important because it determines what kind of crypto can be exchanged or traded and how much each trade will change the price. The liquidity pool is the total of all of the currency deposited on the exchange by every trader. If this pool is small, then every transaction can have a noticeable effect on the price of the crypto in the exchange. This instability makes it very difficult for a trader to predict how much of each currency they can get at any given time.
It was a rough year for bitcoin–and cryptocurrencies in general. Here’s a look at how we got here.
The result of this saw Bitcoin’s highest prices sliced in half in June, with the coin struggling to break out of the low to mid $30k price range until it received a welcome boost from Tesla founder Elon Musk in his appearance at major Bitcoin conference in July.
Bitcoin uses a Proof-of-Work mining system. This means a network of miners computes complex calculations to keep the Bitcoin blockchain running. Miners earn newly minted Bitcoins as a reward for their work. Proof-of-Work allows Bitcoin to attach a physical value to its transactional system. A Bitcoin is worth a certain amount of computing power.
Fiat currency. A fiat currency — such as dollars, euros, pounds, or yen—is a trusted medium of exchange, or legal tender, that is issued by a recognized government or authority. U.S. dollars, for example, are backed by the “full faith and credit” of the United States government.

Notes: This figure plots weekly averages of log price and log network size (log of unique active addresses) of Bitcoin and Ethereum over the period from August 2015 to January 2019. We normalise both the time series by subtracting their mean and dividing by their standard deviation.
The late 1990s and early 2000s saw the rise of more conventional digital finance intermediaries.
