My guess is the numbers who have decided to stick with it because they're having fun or it's social for them is higher than just a few. I'm not sure if I could put an accurate percentage on it, but my gut feeling is one in four or five people would say that. 20-25%.
Those that are here to help people, are somewhere in that range.
Those who came here to make money, definitely larger, but probably more like 50%, or even a little less. The reason is, if you're here to make money, and that's your sole intent, without any other reason, you're probably not going to last long, or you're going to find yourself burning out more often, because you don't have a solid why. Since making money is a what, there needs to be a reason for making the money that is more important to you. Otherwise, you will look elsewhere for fulfillment until you find it.
Applies to every other money making opportunity, not just Steemit.
I'm sure there are quite a few that just enjoy writing. I'm one of them to a degree, but I wouldn't be spending nearly as much time as I have doing this if there wasn't some payment involved. I couldn't. I'm justifying it now, and only to myself, because I fully expect STEEM to rise in price before next January, hopefully sooner. If it doesn't happen within the next three to four months, I will not be able to justify it to even myself.
The way my timing works, though, is I will miss out on the moon shot which means I will also miss out on the opportunity to do more. I really hope that doesn't happen. :)
