Re: NobleCoin[NOBL] - 8% PoS | 1Yr+ | MARKETPLACE | PAY | GIFT | CHARITIES/MERCHANTS
Add: When looking at the top 50 in the rich list https://chainz.cryptoid.info/nobl/#!rich , it looks like just under half are minting on a regular basis, and really wasting their coin age in the process since those are 7 million NOBL transaction sizes and up (the largest is minting a 143.5 million transaction size and is probably missing out on 90% of what could be minted if that were broken up into at least 70 smaller transactions).
I suspect the biggest single addresses are owned by exchanges. Possibly Cryptsy? Not sure if they want to spend too much time tinkering with all the wallets they have to achieve best minting results.
However you are right they lose most of possible rewards. So the incentive is there. PoS II works the way it was designed
Note to all people keeping their money at exchanges - it is fine if you are actively trading. However if you are not concerned with short term swings and want to keep your noblecoins long term it is better to setup your personal wallet and split your holdings into several transactions of sizes between 100 000 - 250 000 coins. I am happy exchanges stake coins since this helps securing the network, however it is unlikely they are going to do it in really efficient way. Common good is to achieve highest possible difficulty. And this can be achieved when people spend little bit of resources by staking when their computer is on and little bit of time adjusting their transaction sizes.
