Nobody else could ninjamine besides Steemit Inc.
Imagine the following scenario:
You're taking part in a car race. There is going to be a reward, but there is no knowledge about how much you can win. You participate anyway.
The person who organized the event & gives out the reward, is also driving in the race.
Once the race started, you seem to be in a good spot. You're not the first, but also not the last. The owner of the race though, has this incredibly maxed out car, probably worth a million dollars.
Suddenly, the owners car stops. You're not sure what happened, but you continue to drive anyway.
However, there is a message being broadcasted about the race having to be restarted. You're furious. How can this be? You suspect that the owner decided to restart it. You decide to drop out of the race as you're not sure whether there will actually be a reward at the end.
Seemingly, quite a lot of people had similar thoughts as you and the race lost a lot of participants. You think to yourself, that the owner of the race has it even easier now, since there are less people participating.
In the end, you decide to never take part in races from this owner again.
This, basically, is the story of the ninjamine.
Now, I ask you: if another person participated in the race and finished it, is there a difference between the owner of the race & that participant?
