The quarterly growth in total cryptocurrency market capitalization in the first three quarters of 2017 equaled 46.47%, 267.39% and 54.03%, respectively (see Table 1.1). The deceleration in growth in the third quarter was due to the restrictions (bans) on circulation of cryptocurrencies introduced in several countries, most notably in China.
The market capitalization of Altcoins (the alternative cryptocurrencies to Bitcoin) continues to increase steadily. Their share at the cryptocurrency exchange increased from 12.33% to 58.16% during the period from January 1, 2017 to July 1, 2017, but showed a downward trend to 51.34% in the third quarter based on data as of October 1, 2017.
The exchange rates of Ethereum (519.78% and 453.91%, respectively) and Litecoin (40.00% and 492.17%, respectively) demonstrated very vigorous growth in the first half of the year. Bitcoin exchange rate growth equaled 11.53% in the first quarter and 125.43% in the second quarter. Bitcoin showed the highest exchange rate appreciation in the third quarter (77.28%), while the growth of Ethereum and Litecoin was 6.83% and 42.85%, respectively. The growth in cryptocurrency market capitalization is nearly proportional to the growth in their exchange rates, but is also contingent upon the volumes of new coins mined.
