There is no denying the fact that, it is profitable, depending on how much is made per post. Like you have pointed out, $2.11 is a lot in some countries. For instance, a dollar is 360 naira (local currency) here in Nigeria. $2.11 = 759.6 naira, meaning, in a month, it is, 22,788 naira. Minimum wage is 18,000 naira. That says a lot. With more active users, steem price would definitely get higher, and the prospect of it all, would be amazing.
