>>4104755Success is always just a vague and subjective metric, so it depends on how they themselves would measure it, what their goals are and when they would be satisfied.
I'm leaving aside the "I just want to stream for myself as a nice distraction" hobbyists aside, also those who'd only give nebulous "I just want to make my fans happy" non-answers.
For most people, success would be reaching the "can quit my day-job" level. For some people that would already be the end and enough, and a few others are driven further by personal ambitions beyond just self-sufficiency into some vague idea of "stardom" or whatever.
But let's stay on the money thing, because that is the most basic issue at the heart of most of it, and without enough money you'd not be able to continue streaming anyways (unless you have a source of income to pull from elsewhere). Every other numerical measure of success is just incidental to this basic root then. Views? Only matter insofar as more views mean more ad impressions, therefore money. Subs? More subs are only important as for they're supposed to bring in more views, and what are those good for? Right, money. (as an aside, a big enough level of subs and views can also start landing you sponsorship deals, which again you guessed it, means more money). Memberships and Superchats? No one needs to ask, directly money.
As for what amount of money is "enough" (to do whatever you want to, whether it's quitting your day job at the least, or buying a villa at most) depends on your expectations and preferences. Is 1000 bucks a month enough for you to live off of? 3000, 5000 bucks rather? Or do you want to make five figgies like the very tippy top of Vtubers? It all depends on your individual goal for "success".
