Last time I checked, this was an IPO. Why would anyone want anything to do with an IPO coin when the coin creator can create hundreds of mule accounts, donate 10 BTC with all of them, get 99% share of the coin, then have all the BTC he spent return to him since he's the IPO provider. IPO is just a license for infinite premine + making lots of BTC from whoever sends him some.
This is why the price of NXT is kept artificially high. Anyone with a primitive level of TA skill can figure out that there's a very small number of large holders manipulating the market.
I can't speak to NXT, but I can speak a bit about BitShares. My understanding is they had someone in the Carnegie Mellon CS PHD program quit to work on Bitshares along with other extremely talented folks. This isn't just some random anonymous people on the internet. I'm not even sure what you're talking about "IPO coin". The bitsharestalk.org has about 5000 accounts, and a lot of them are Chinese. There wouldn't even be a need for "mule accounts" as you use your private key to redeem the fruits of your donation.
I'd prefer POS over Bitcoin's POW which is charging users 10% inflation just for network security. Actually if Bitshares followed that model, the initial inflation would be approaching infinity at the start. We forget how bad it was in the early days.
Why do you want your money supply inflated to pay for network security ?
