The reason why BCH is struggling to recover is because people lost interest in it. They're tired of seeing new Bitcoin forks with claims of being the "original Bitcoin". Each time a new fork comes out of Bitcoin Cash (like Bitcoin SV for instance), the project's image/reputation declines. The hash wars scared off many investors due to the instability of the BCH network. Businesses and merchants want something reliable and secure, so they'll resort to Bitcoin instead.
Believe me, BCH is nothing but a "glorified Bitcoin" with an increased block size. Simple tweaks won't make the project stand against the original one in my own opinion. BCH needs something new, funky, and fresh if it wants to gain traction. Otherwise, it'll struggle to reach a new ATH. Only a bullish Bitcoin could save BCH from going all the way down the drain. Just my thoughts
