"if #pob is listed on a centralised exchange (binance or kucoin) now, what effect will it have on the token, positive or negative"

First let me say a very good job well done for some of the brilliant question asked in this platform.

Regarding the question the truth is that having pob stand independently in which we dont have to convert other crypto to hive before converting to pob will be a great advantage as many crypto trader who love to buy crypto when price is down will like to buy more pob and sell when it is high again. Just like @vikbuddy said "POB is still too young to be considered as Independent Identity or compared with other platforms" i still want to strongly believe we may get there with time.
