Why are the tokens exchangeable for NEM only 2 weeks after the NEM launch?
logistical reasons.. the devs can only distribute nem at a certain pace.. it could be shorter than 2 weeks.. just better to say a longer time and be early than shorter time and be late! they may find a way to automate it also so that could speed things up too. i have a fealing real nem will trade on the nxt AE before it will on any other exchanges!
It's not 2 weeks.
8. NEMstake tokens will expire and has no more conversion power after the completion of V1 blockchain (about 2 months after the official launch). All NEMstake tokens will be destroyed by sending them back to Nxt genesis block.
