depressing when your importance slides

do exchanges build up a bs level of importance on the NEM network?
You don't need to be depressed.
In Poloniex's case, they use user's fund in harvesting less than 25%.
(More than 75% is stored in cold wallet, and do not harvest.)
This is less than ordinary nember's use of xem in harvesting.
Perhaps, ordinary nember's harvesting might become higher owing to their not-doing-harvesting-fund in coldwallet.
