There should be no premine. If devs want coins they can start mining when we all start mining.
I'll jive in as the guy who contributed the logo and graphics for the project, personally, i'm also a human with bills to pay like everybody else. As excited as I am over Expanse and the talent behind it, I still can't afford to work for free and I doubt neither can James, Dan or Christopher. I honestly would not dedicate my time to it if I knew there wasn't a bounty coming or the chance to get coins early on. It's not that I don't value the project, but my time is valuable too, I got a 40 hour a week deadend job like everybody else so if I am going to step up and contribute I hope to get some kind of return. I don't have the necessary equipment to mine and I also don't believe I should have to sacrifice and make the big miner farms rich while I am left with having to buy off an exchange at rising prices when I am the one contributing blood and sweat to the project, something busy bodies on here can't say.
Unfortunately in my almost 2 years in crypto now I think the issue of premines are the most dramatic issue people have ever made a deal out of. Of all the scam coins I've been through and can count off the top of my head, the vast bulk have never been problems with devs dumping premines but devs just frankly abandoning the coin after 30 days to go create another coin, rinse and repeat. Frankly most don't even need premines as most just ninja launch with their big miner buddies and gobble up all the coins in the first day anyway. Trust me, a 0% premine has never EVER prevented or insured against a coin from being a scam, all it does is drain resources or incentives for honest developers.
Which would you rather have, a developer team with the necessary resources to stick around in the long-term or a fly-by-night crew just looking for a quick pump and dump? Now I do agree a premine shouldn't be exorbitant or obscene but a respectable amount that even if dumped immediately overnight on an exchange wouldn't completely collapse the price of an asset.
