You are late.
Some dapps like chainbb, eostalk esteem. they will upvote comments on their dapps. maybe 0.5-1$. Those days many people use multi accounts to comment. maybe can get 50$ per day.
and before, when you register steem account, you will get 30sp in your account , if you get 10000 account ,you can get 30w steem. i know many people get much sp by this way .
so , you can get rich by this way ,but late. If you miss the chance, it will never come back.
Now, i can tell you , if you want to be a steemwhale, the only way you can do is keeping writing/sharing.
