We thought this for a long time. 30% will be distributed during a year of mining, not for a few days or weeks. We believe it is the best way to make a fair distribution. But equally we will read the opinions of everyone before launching the maintnet.
That is a good idea. Just be fair between POW and POS so many people will join this project .
It's bad idea imo and POW distribution is the worst. Consider to use LISK-like or similar scheme
Devs won't get any money from POW miners - the miners will be just dumping the coins
