This is very important. Everyone involved with Steemit/Steem needs to know about this. Then somehow get at least two primary questions answered:
Who is/are the "whales"?
We use that term on Steemit, but I understand you're using it in the broader market sense, or at least how it pertains to cryptocurrency. In other words, it's not necessarily someone associated with Steem or Steemit, or for that matter even friendly to it.
What is/are their motive(s)?
I like your answers, @dragosroua. It would be great if there was someone doing some "advertising" via the markets. "Hey! Look at this! It's a good buy!"
Not so good if it's just someone speculating, or finding a relatively small space to pump and dump, while making millions with smaller price moves. It's worse if they're hoping to break it (scary if that's even possible).
No idea. Also, I don't know if they are Steemit related or just random wealthy people.
Most likely getting rich.
