What number if this coins, required for masternode?
Masternodes will become available at block 75,000 and require a collateral of 15,000 WAE.
Now, it's about ~$30! Very nice price.
But I believe that the price will fall a little more, because there are so many people who have received millions of coins during the award for block 5600.
With time the overall coins will disperse. That was essentially handed out in order to get the coins going and moving around.
