Here's a great post from gutshot5820 in the Ehereum thread
Lets put the fundraiser in simple terms that everyone can understand. Everyone should agree agree that all investments should have a proper risk/reward ratio. This project itself has a lot of risk and potentially a lot of reward, so neither can outweigh the other. Now lets look at this objectively from that perspective.
Ethereum project;
Risk = Very High
Reward = Very High
Founders;
Risk = 0%
Reward=100%
Early adopters;
Risk = 100%
Reward = ?
Put that on a graph. Does that seem like a fair transaction to you?
If Ethereum fail, the dev will still sit on thousands of BTC. It doesn't feel quite right to me.
On the other hand, if NXT failed, BCnext would have got 21 btc, not even enough to pay for his dev time.
The risk/reward was and is a lot more fair in NXT than in any other project like Ethereum or Emunie.
On top of that, Nxt's development is much transparent. You can ask any tough questions on this tread and several other threads regarding the technical issues and doubts and you get answers. I have not seen other projects with this kind openness and confidence yet.
