Okex is not large exchange nowadays, you should try it like binance, huobipro, or even kucoin and bibox is better than okex. I doubt the price can keep this level, hope the price will pump.
It's better than only listed on IDEX or forkdelta. Being listed on okex means this token still has potential to get listed on bigger exchanges. You can't get listed on big exchange in short time, they have their own criteria before listing some tokens.
