Bitcoin's (Bitcoin) market capitalization has dropped by 59% - from 613 to 252 billion dollars in the first quarter of 2018, but the most popular cryptocurrency is still not the biggest looser.
With 50% decline during January-March 2018, Bitcoin looks quite descent as compared to many large altcoins. For example, Ripple (XRP/USD), Bitcoin Cash (Bitcoin.Cash) and Cardano have lost more than 70% of the cost in due period.
