early adapter need some reward. why would people mine this when hey will get no payout
If there is any quantitive amount of interest in the coin from large pools, it will instantly be not solo-mineable. If the coin does not gain attention & interest pre-launch, then there may be no need for the low initial rewards. Thats to be determined I suppose. Depending on the reward & block timing structure, a few 100 blocks could be rifled threw in a matter of a few minutes. A rolling start is good for a few things: 1) It prevents Shady pools with source code's that start earlier than everyone else (usually only seen when a coin is also to be launched on a trading market at the same time ) 2) It allows every one to get onboard, and not mis out and when actual rewards & KGW kick in, its fair for everyone. I'm sure theres other reasons that are pretty obvious too.
