using one coin and then re-issuing another coin based on same is not a good idea
I don't agree. This way long term nxt hodlers don't have to spend btc to get tokens of the successor platform (in fact they don't even have to do anything and still participate in two airdrops). Of course, they can also choose to take profit now and sell tokens to newbies like me before the ico ends. Overall the devs seem to act responsible and rewarding towards long term investors.
