Dunno what you're smoking. If you want to be a successful webnovel author, step 1 is to write a halfway decent story. Step 2 is to post that shit on every platform available - including the "most popular platform", whichever that is - and begin the most glorious and terrible campaign of viral self-marketing the world has ever seen.
With services like Patreon allowing for unified monetization, the platform(s) you choose to post on are more another form of advertisement than anything else. Unless you sign on to something like Qidian's more restrictive platform, ofc.
Since the OP is asking about JJWXC... I suppose they might end up stuck in a contract with someone. In that case, let's wish them luck and hope their story is good enough to stand out.
