It is obvious that for a miner and/or investor a coin with no premine it's the best.

On the other side the dev/devs wants to get something for their work, hardware, maintenance, etc.

So in my opinion the fair way to keep the investors and devs happy is to make a coin with % (1%-5%) from block reward that goes to dev or coin maintenance.
This way the investors are not afraid the the dev will dump the premine and also the dev will not get all the rewards form day 1, he'll have to work and get the rewards block by block.

1%-2% premine it's also acceptable for a coin without masternods or early POS because that 1%-2% could turn in 10%+ because or masternods/POS early rewards.

Good luck with your project!
