0.5% premine isn't much on a few days POW/POS coins, but on a pure POW coin it's huge. That 0,5% is like full 7 days instamining...
The dev is gonna have too much coins at the start. Multiple times more than everybody else combined.
And considering the dev is on a newbie account, I'm gonna pass. Anonymity hype with huge premine... I've seen shit happen too many times in situations like this.
GL to everybody else.
