Your point is ok however still flawed with a lot of limitations. Let me know a platform that is not fraught with scammers ? FB?
Steemit , on the other hand, will give you the opportnuity to earn even if you are not a whale !!! I know many members from Developing economies (Nigeria, Indonesia , Pakistan , India , Ghana etc) that started here wihout money and are very comfortable now. They based their strategy by commenting and earning steem , powering up, joining communities and grow gradually...did FB give them such chance or make them selfie junkies?
