Yes, you can definitely make some good money with STEEM. It all depends on your SP though. You need a lot of it. Also, the more you post good content and curate other peoples content the more potential you have to earn. Starting out it is going to be a slow process. It is not a get rich quick thing. I know people that have over 100,000 SP and they earn the equivalent to $150 + a day. Depending on where you live in the world that is good money.
