Is BCH a real replacement for BTC?

Hi guys, I have been researching the technology behind cryptocurrency for a while now, currently hold a few bch and just had a few questions.

Does BCH stay true / similar to the original whitepaper of BTC, to be used as decentralized electronic cash? - additionally, has it been compromised at all by bad actors, as is believed to be the case with BTC and blockstream?

And does BTC have any real value / is it worth investing into, given that it can't be used as a currency due to transaction fees? The store of value argument makes 0 sense to me as value comes from purpose, so to me BTC seems useless, and is being driven up by people who know nothing about it and don't want to miss out, and the people supposedly controlling btc behind the scenes.
