Yep, and it really doesn't matter - they can be a bit greedy but also be smart and realize that their ROI will be much higher if the steemit platform succeeds. When a user is investing real money in steem, it's obvious that they'd want a solid profit, and in the crypto realm, the gains can be several fold - 10, 20 or even 50 times a year ! .. Not just a 2-3 fold growth, and for such strong upward thrusts to occur , a great reputation is a must, it's simply not attainable "just with time" or "just because the crypto markets are very bullish right now" . My point is , it's in the investor's best interest to create/ curate content honestly, make new authors feel welcome etc. These things don't show immediate results (or immediate profits), but will be the cornerstone if we are to succeed, and see prices of $10 or $20 per steem.
For myopic greedy pump and dump investors, there are actually several other options objectively better than steem - numerous ICOs, scamcoins being pumped on a regular basis, you can make more profits there than steem if you keep up with the news and updates
