There can only be a maximum of 1k MN holders.

10,000,000 max supply / 10,000 xnode for MN = 1000 Total Masternodes available

But their is 1 million tokens for the investment fund held by the developer

9,000,000 supply / 10,000 xnode for MN = 900 masternodes available

Current coin supply is 1139357 today

1139357 xnode - 1,000,000 = 139357 / 10,000 xnode for MN = 13.93 masternodes available


Mining on a pool for a MN will take some time to get as mining rewards are 0.5 xnode per block, MN holder would get 1.5 xnode.
Trading on the current exchanges would be the most profitable way to get a MN in a short time with the current low price.
