I really like the idea, since I am an analyst, but unfortunately I do not have enough capital for investing. But how can I protect myself if I provided quality information, but I received either too little reward, or did not receive it at all. Unfortunately our time is pretty much scam

The content creators have to figure out what resonates with the network to obtain the maximum yield. This is no different than formatting something in the relevant way for an ebay listing, or a craigslist post, if you do it wrong then nobody will pay attention to it.
For some time, we will be subsidizing selected content contributors from our company treasury, as they learn how to provide the best information

It turns out the rating of authors who provide information, will also be introduced?
