1st There is no exchange available and who knows when will it be. Good luck selling those coins on peer 2 peer, you will have to compete the devs for that. And getting 2 coins per block, will take a while to stack 10k
2nd You probably have no idea how many nodes will be sold on the pre-sale. They have a premined equivalent to 308 they intend to sell. And drop a few coins as bounties.
3rd Block reward at this point is 2 FIX / block. There will be another 18 hours or so, maybe more until you will get decent rewards for nodes.
I really think you should see this before rushing to buy a node... There are already 22 nodes up and counting.
2) You can check all the transactions made on the blockexplorer from the premine wallet and you will see how many coins went to presale, bounties and contests.
3) It is better for every coin to have a solid network/community before starting hugh ROI phase. Noramally there is like 1 wallet getting everything, with starting of at 2FIX we are avoiding this and everyone can participate getting good rewards.
With 100masternodes online the yearly ROI will be at approx 5800% when block reward is 220FIX
