Litecoin was created in 2011 by a Google employee Charlie Lee. Currently, this cryptocurrency is one of the largest by market capitalization. Litecoin was created as one of the first forks of the Bitcoin blockchain. Also, it is safe to say that Litecoin is one of the first altcoins. While Bitcoin is based on SHA-256 algorithm, Litecoin utilizes a lighter scrypt algorithm.
Pura (PURA) digital assets seem to be currently inactive. Originally, the developers’ idea was to leverage anonymous and instant transaction through offering PURA coin. PURA is the project of the Dash team.
Dash was launched in 2014 and changed several names before becoming Dash as we know it today. The initial goal of the project was to create a cryptocurrency network which would operate faster and cheaper than Bitcoin and would be capable to maintain more privacy. Holders of large amounts of Dash have different privileges (Instant Send, Private Send, etc).
Dash is an open-source project. It has its own blockchain. The currency is supported by many crypto wallets and it has gained significant market capitalization. Another great achievement is its numerous partnerships including cooperations with Western Union, web stores, etc.
