The listing of pob on a popular exchange sites like binance won't be the best for present pob.
Pob is still in it's developing stage and at the same time in it mainnet because it's already tradable and exchangeable but it's still mined by creating quality content and engagement.
So pob must first not be easy to acquire anymore like now it must be so scarce that people would wanna buy but for now people will earn it for free and just go and sell it.
Let's not be in a hurry,those that sell pob now will regret it later because there would be scarcity in the future.
After enabling scarcity,then if pob is listed on a popular exchange sites it will be of a great advantage
This is not a negative effect listing pob on a bigger exchange site does not have anything to do with pob use case.
Pob already have a use case that is strong enough as a reason for people to buy pob. Even the listing of pob honey popular exchange site will boost the use of pob trading and many transaction and with that the value of pob would be so high.
The best thing that can help pob right now is if pob is listed on a popular exchange then,it will increase trust and encourage more staking to earn more
