Hi vnb54270,
Don't you think (minimum fee)/(total supply) is too small considering the nature of this coin.
The MAX_MONEY limit is 2 billion datacoins.
The current money supply is 27,125,817.51783475 datacoins.
We're 1.35% through the distribution cycle.
The nMinRelayTxFee is 5 Satoshi.
The nMinTxFee is also 5 Satoshi.
Miners may adjust these thresholds with the -minrelaytxfee and -mintxfee knobs, respectively.
The fee for storing data doesn't appear to be too small at this point in time considering the current size of the blockchain.
If Datacoin were a 500GB blockchain then maybe the fee is too small.
It would appear datacoins are being used for both their intrinsic utility as well as speculation.
There is room for both of those value propositions with the current fee structure and money supply.
Also, it is better if small coin is burned to store data. Currently even small miner can dump whatever garbage data to blockchain without paying any cost.
Of course there is a cost. The miner first secures the network by performing proof-of-work in order to earn datacoins.
Then, those datacoins are used as inputs in a transaction along with the fees in order to pay for the garbage.
The more miners there are the less the above will resemble a zero sum equation.
Best Regards,
