Dash (formerly known as Darkcoin, also known as Digital Cash) is a digital currency that has quietly crept its way into the top 10 largest cryptocurrencies.
Ether is the other mainstream currency alongside Bitcoin. Among the thousands of virtual currencies, Ethereum has the second largest market capitalization in the world, after bitcoin.
Litecoin was one of the first cryptocurrencies to enter the market. When it was first launched in 2011, it was known as "Bitcoin Gold and Lite Silver" alongside Bitcoin because its blockchain was mostly derived from the Bitcoin code.
