With the right plan and promotion this can be huge!
I read yesterday about one cool promotional feature for PoS type coins - multipool. It can help with distribution and will affect positively the Qora price.
People on this kind of multipool are mining most profitable scrypt coins and pool automatically sell this "scrypts" and buy PoS coin and send it to multipool miners.
If you think about it, you'll see that this kind of multipool creates:
1) buy support on exchanges -> and this leads to price growth
2) it helps with more wide distribution
3) it creates more "transactions", which is good for "minting"
4) everybody who want PoS coin, but can't buy it for BTC, can "mine" it.
