3Litecoin
Litecoin is an alternative to Bitcoin that aims to fix several issues that are holding Bitcoin down (or are at least perceived to). It’s not quite as innovative as Ethereum, and its value is mostly derived from solid user adoption. There’s also a key difference in leadership. Litecoin is led by ex-Googler Charlie Lee, who’s active on Twitter and transparent on what he’s doing with Litecoin.
For a long time, Litecoin was a distant second fiddle to Bitcoin; far less valuable, but always there as a slightly more forward-looking alternative. But things started changing in May 2017. First, large crypto exchange Coinbase adopted Litecoin, alongside Bitcoin and Ethereum. Later that month, Litecoin adopted the Segregated Witness (SegWit) technology, which fixes the issue Bitcoin has been reluctant to solve; it adds capacity to the network and lowers transaction fees
