Based on the OP: Total approx potential coins from POW: 900,000, lower with mixed POS at block 2700. 3 days mining.
Then, only one pool mined 83.33% of the POW coins in only three days.

Now, please find below the list of the people who were mining in that pool:

We can see that the top #1 miner have a total of 1,105,372,766 shares.
If we add all the shares from the #2 miner to the #15 miner, we have a total of 480'616'568 shares.
Then, the #1 miner of that pool had 56.51% more shares than all the 14 others top miners for one round.
This means that only one miner had 56.51% more chance to get the reward from the block than the 14 others top miners.
Every one can make his conclusions but mine is that there is someone waiting to dump a bunch of coins and when I see the dev saying he hold only 4,8K, I laugh much
