25% for development does not mean 25% for the devs.. the devs(5 people + (i think)who ever else they think deserves a reward for helping nem be it in marketing or what not.) will get 15% split between them MAXIMUM and only 10% of that 15% will be distributed at launch. the other 5% will be slow released over time. the rest i would think bounties, hiring other developers and what ever other costs are incurred from development/marketing/promotion etc etc. devs wont get 25%.

you only need nxt to buy nem to buy a stake prior to launch.. we are currently in the redemption period and the majority of stakes have been sent back along with a nem address so that the nem can be redeemed for real nem. there is no other way that we could have traded stakes prior to launch other than issuing assets on the AE to people who registered for a stake. there is no "fish" in nem.. i can assure you of that. the devs have worked tirelessly for nearly a year to produce the brilliant platform that is nem. they are also not launching nem until multisig is ready so that the community can be completely confident in the fact that no one is going to "run with the money".
