Of the approximately 650 crypto-currencies available worldwide, Bitcoin
remains by far the largest. In January 2017, Bitcoin
had a market capitalization of roughly 12.6 billion euros, about 15 times as much as its most valuable competitor Ethereum and nearly 55 times more than Ripple, which completes the top 3. Even combined, the market caps of currencies two to ten are worth only a fraction of Bitcoin's value
, suggesting that Bitcoin's lead will continue in the foreseeable future.
