This is definitely a question that I've seen discussed in the passed few weeks...

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

I wrote about this a few weeks ago and my thoughts are pretty much the same. It is frustrating to exchange POB to Hive and then send Hive to another market to exchange but for the time being this is the best option. When POB has a reason to be bought and sold in the market then POB should be there. It's not easy to lobby these big exchanges to put your coin up and then when you get there and find no activity it is only loss. POB had better use those resources to develop the environment and usage not to lobby the exchanges.
