I think the developer of bitcoin cash is now trying to be more competitive in the marketplace knowing that there are many new altcoins which is very hyping at the moment such as uniswap and chainlink, this is really a good move for them to make a hype as well so many people can also acknowledge them as one of the best top rank cryptocurrency.
Not really; they can say goodbye to their top 10 position after the fork as the market cap will be split into 2 separate, competing Bitcoin Cash's. On November 15th 2018, the day of the last hard fork, Bitcoin Cash was $420 a coin. Today BCH is $215 and BSV is $155, so those two coins combined don't equal the price of BCH pre-fork. There's no reason to think this time around will be any different.
On a side note, it would be a perfect opportunity for Roger Ver to finally drop the word "Bitcoin" from the name of his coin (seeing as how BCH is obviously not replacing BTC as
the Bitcoin, as was his claim and rationale behind keeping the name "Bitcoin"), but being as dishonest and greedy as he is, there's no chance of him actually doing that.
As another aside, BCH is currently at all-time lows against BTC.
