In the crypto world, there have been various upgrades for the purpose of offering a better service. Just as Bitcoin was upgraded to Litecoin, Litecoin was further upgraded to Litecoin cash to offer a better service.
Litecoin cash is a fork that has higher max supply and has a better difficulty adjustment. It was developed with a different ideology from the snapshot of the existing code from Litecoin. It has a wide and ready pool of mining power to tap, state-of-the-art difficulty adjustment to react to network hash dynamics, a mature and fair distribution. I do use it for day to day transactions, transactions are fast and secure with low fees.
It runs its own blockchain and combines features of some well established coins.
Finally, it has high legitimacy from my experience and I highly recommend it.
