Litecoin, otherwise, is actually a younger brother of BTC, and Bitcoin Cash and it is accepted by the huge community.
We know many people have dogma like Bitcoin is gold and Litecoin is silver. Many professional traders said Litecoin will follow and mimicking Bitcoin market but the truth is Litecoin hasn't made any tremendous spike in term of Bitcoin increasing value. I'm sure soon Litecoin price will make a new all-time high.
About Bitcoin Cash, I doubt it accepted by the community, it still has a lot of controversy in the cryptocurrencies scene. I believe cryptocurrencies scene community is hating Bitcoin Cash instead of support its existence.
