Theres only 1 thing I can add here; there are different possibilities --
- you can spend 5 mins on 1-pic shitpost, and make a daily spam with it (plenty of users is acting like that)
- you can spend 4, or 14 hours (I have articles that take me even more, like some accounts on my year's reading) to collect said $20 under a post
- but you also can make less quality post, and spend less than 1 hour on creating it.
...there are different possibilities, and rewards are not a mechanical derivative of time invested. (Thank God, this system does not work under the control of egalitarian socialism). So, different tactics and methods are possible for a user who wants to spend less of his time and get more money from it. Users indeed may have different goals, but still ... you cannot (or, rather: should not) do something for the pure sake of money only. Practice has shown many times in the past that this leads to bad results in the long run.
