Nothing wrong with cashing out and taking gains, my point was only that some accounts only do that. There are different ways of bringing value to the platform but if they aren't producing good content to attract others, aren't engaging meaningfully and aren't holding anything in their account to help with inflation then I would say that they aren't bringing any value. This does NOT seem to be the case with you.
Regarding good content creators that didn't do well, it's hard to know the circumstances of such cases but I'd say that "good contentent" is subjective and building a following takes a lot of time on any platform so people need to be willing to slug it out for a time. some have unrealistic expectations when they start, thinking that they are going to have a massive following after only being on the platform a few weeks or months and that they will earn a lot on every single post. I think it took me almost a year before I made anything over $2.00 when I started and then it was up and down on each post for a long time afterwards. If a person were to join a new platform like TikTok and start fresh without pulling a following from other accounts they have, how long would it take that person to get 10-30k followers to start making money on the site? It's a similar situation if we consider the relative size of each platform. A person can't join a new site and expect to earn huge in the first year or two (though there are cases where that happens I'm sure).
