Exactly. Trading volume doesn't reflect anything. After all, the crypto market is heavily manipulated just like the rest of the markets in the mainstream world today. What determines Bitcoin success is transaction activity across the Blockchain. And so far, Bitcoin is the leading cryptocurrency in terms of mainstream adoption. Neither Bitcoin Cash, Bitcoin SV, or other Bitcoin-based forks, will be able to topple the original Bitcoin in the long run because people trust it more than any other cryptocurrency on the market today. It's that first-mover advantage which gives Bitcoin an advantage over other cryptocurrencies on the market. Developers from Bitcoin-based forks may try to hype their cryptocurrencies with shiny new features that are yet unproven in the crypto/Blockchain industry. But they'll ultimately fail, since people are seeking stability/decentralization than all the other way around.

With BCH and BSV in play, developers can experiment with new features before they're introduced on the main Bitcoin blockchain. The more forks there are, the better it'll be for the advancement of crypto and Blockchain technology. This creates a network effect that'll turn out to be extremely beneficial for Bitcoin and its competitors. Remember, it's not about Bitcoin. It's all about how Blockchain technology can make our lives better by decentralizing finance in every way. As long as crypto delivers as promised, nothing else matters. Splinter coins (BCH and BSV) claiming to be the true/original Bitcoin is more politics than anything else. Just my opinion
