LCC is a fork of the more familiar cryptocurrency Litecoin. The most apparent benefits of this fork over its predecessor are really for miners. They've brought back to life the legacy SHA256 algorithm, effectively allowing for miners with older hardware to mine a new coin. They also claim that fees are significantly lower than that of LTC, but LTC's fees are already low enough that the difference would be negligible there.
This coin does not seem to have been able to take off the same as Bitcoin Cash has, despite being offered for free to LTC holders. While this coin does offer some distinct advantages to those who are looking to mine their cryptocurrency, the features for those who are purely investors or consumers are lacking.
A Litecoin Cash investment leaves little upside if you're not a miner interested in SHA algorithms or better difficulty management for your mining rigs. At best this is a mediocre fork of an asset that did not need a fork, at worst it's purely a money grab meant to cash in on a top-level currency's branding and position.
You can easily buy Litecoin cash on several exchanges, but there are not very many high volume options available. Bitcoin is the highest volume trading pair here, but if you'd like to use US dollars to make your trade there is a viable option for it available. However, you should make sure to withdraw your investment immediately from the exchange. It's not safe to leave your coins on any exchange, but especially on some of the options presented here.
The best way to store your coins is by using the official wallets which are available for download from the coin's website. They have installation packages available for Windows, Linux, and Mac. If you would prefer a mobile wallet, they also have an integration available with Coinomi for Android and iOS. As always, make sure to always back up your wallet file or your seed key in a safe place in the event you need to recover your wallet.
