Like it has been said previously, the mentioned scenario are not possible at this time, and I say NOT POSSIBLE:

1) you can check on the blockchain explorer : the first addresses holding the said 1 millions coins have only 1 transaction, the initial one.
     This shows without a doubt that they are not selling the coins or parking them.

In fact, you can see that only 2-3 adresses in the top 20 are parking the coins, and these addresses are also mining. They belong to regular people.

2) They would be incredibly stupid to do that at this stage. The coin went up to 60$ yes, but the amount of "sellable coin" was super low, less than 20.000 MNX. If you do want to get the real money, you just have to wait to reach a proper exchange.

3) If you read anything about the whitepaper, nd if you have any idea how vital the minexbank safe operation is to the project, you would understand why such a testing period is important.

ALl of these comments only show how little you know about any type of project, and how impatient you are. Do your own research backed by facts please, before posting your own FUD needlessly.
