NxT's price is collapsing because one of the original NxT whales (40 million) downloaded a keylog file and presumably close to 7 million has been dumped by a hacker so far and another 33 million will be dumped. He had passwords to wallets worth several $million on a text file on his desktop.
https://nxtforum.org/general-discussion/price-speculation/5440/This does relate to NEM as it is entirely traded on the AE and NxT's price changes has a huge effect. A $500 NEMstake is possible if NxT continues to drop in price.
This is why we are building a feature into NEM that should help prevent situations like this. Welcome to Crypto 2.5
