Does your NEM have to be stored in NCC to be able to harvest? Or will harvesting be possible in an exchange account?
if you have your coins in an exchange, the exchange will benefit from your coins. not you.. unless they feel extra nice and decide to give you interest on your deposit, which would no doubt be less than what you would gain from harvesting.. also after seeing soooooo many exchanges get hacked.. would you seriously let an exchange hold all your nem? honest question? bad idea my friend.. bad idea..
