If the first reward is granted on day 2 of the 1-10 period (for example) and the next one is designed to be released in between 10-20 of the month all the miners will switch off their rigs and wait for the next period to start mining again.
To avoid this you wold have to forget about fixed periods so that the next period in which a commie block is given starts right after the first is found.
that's a great idea and i thought about that -
problem is then that just creates another gap so for example if its day 4 and its been rewarded, are you suggesting that the 2nd reward can now occur straight away ?
well if it happens to occur on say day 5 now we have 2 /3rds given in 5 days - which really gives an incentive for miners to walk away -
the social science of the 3 in 10 day blocks i thought was better.
We have to step outside the box - not all miners are created equal.
mining psychology A - some miners are just agnostic, these are "profit miners" they see electricity; return break even profit , that's great that exists and we applaud that.
B - however some miners believe in the product, so this is more in keeping with grass roots "bootstrap" idea, don't get me wrong this is not fairy land , they have a profit in mind , but its not a short term "back to paper" profit.
So you see Miner A has less belief in "cryptocurrency" and See's mining as a way to get paper (fiat) ( completely rational )
Miner B is more invested in the idea of Crypto and is utilizing the tools immediately at his/her disposal for an investment in the future.
so for example the C - Bloc may certainly not provide enough incentive for group A but could for group B, group A can certainty participate and the extra hash will not be a problem, but its more likely that group B will participate more consistently.
again this isn't "hope and change" this is " the price in paper (fiat) is not enticing enough" for group A.
now the second part of the story ( which you would be well aware of )
a group of "actors" trying to exploit it - i.e turn miners on to get the reward to dump it, they are welcome to do that also, all things being equal they use PoW to do that , that's fine they had a cost it was returned in hash to the network, we thank them. if that occurs constantly we would review the process, and this just then leads to more improvement:
and so goes Crypto currency evolution.
