How much NXT you earn from forging depends on transaction volume. NXT users is still a small pool of individuals and transaction volume is low. Transaction volume will increase exponentially as we have seen with Bitcoin which will increase forging profits dramatically.
I guess this situation is like when Bitcoin first launched many years ago... what motivation was there to mine?
Transaction volume or exponential increases in it don't alter the bottom line at all. They only define the timeline you see in getting there.
A 1000 NXT forging stake will earn you 0.0001% of all transaction fees, which is identical to saying you get 1 transaction fee NXT for every 1,000,000 generated by the system. You will double your 1000 NXT stake after 1,000,000,000 NXT have been generated in transaction fees. How long it takes to generate a billion NXT in transaction fees depends on the average size of all NXT transactions. For every thousand NXT in the average transaction size, a trillion NXTs must change hands for you to double your 1000 NXT forging stake.
Math is math and facts is facts. What's your numbers, or what's wrong with mine?
I repeat my contention: I believe it will be low cost of many, many Raspberry Pis and not the high motivation of many, many forgers that will ultimately make the NXT network a viable one.
I agree the will and desire to make the Nxt network stands and prospers is the strongest motivator. In the near future the transaction will be dropped to 0.01 Nxt. Forging to make money does not make much financial sense.
