The asset issuer hasn't raised the price. They cannot raise the price of what they're not selling at the moment.
EDIT: This is wrong! I realized this after I posted.
jl777 bought up most of the initial offer. To dispel suspicions of 'conspiracy', 'conflict of interest', etc, jl777 divested the shares from NXTventures (which aims to invest in startups which NXTinspect will likely also be auditing, hence the potential for conflict of interest). Some of that went back to the market, @ 2.5 nxt per share. (I don't expect jl to sell at cost, he has a responsibility to his NXTventure asset holders to make $ for them as well). Then some people bought those up and resold at higher prices (I'm late to the party again! I picked a little up @ 4.5, I feel it's slightly overvalued right now, since there are no actual reviews out yet.)
tank, if you're an investor, you should have done your homework, checked the blockchain, read the threads, and you should know all this. (This also applies to anyone else looking to invest.)

To me, nothing was "unfair" about the intial offer. They didn't have to make it a
public offer in the first place, they could have raised funds privately outside of the AE instead. It's their business, their tokens, their right to do what they want with it. They don't owe it to anyone to sell their assets cheaply. But if their goal was also to try to distribute the shares and have more folks with a stake in their service, then there were better ways to do it, preannouncement would be one. (Nxt seems to keep having problems with initial distribution

)
EDIT: You guys are right, the sale @ 5 is by the asset issuer! txid 9180901517660582655 I bought someone else's resell, and I started my reply to tank before Breasal posted.
