PSB is not on Poloniex's radar yet. Needs more volume, it has to make sense for Polo. They need to make money off the fees. Believe me, I would love it to hit Polo...but it's not ready.
Yes the volume is not that great. We're all waiting for the e-wallet but i don't think poloniex will just look at trade volume (example : Pascal coin).
I think after the final release of e-wallet, Polo will think about pesobit and yes, we need more trade volume. Hoping after the e-wallet lunch people will use pesobit to withdraw cash & the volume will increase atomically. I am not 100% sure that everything will go perfect but pesobit have a great future for sure so far.
Again right time to buy more & more.
