I would say its value could increase to over $500 easily in the mid term because if you compare it to a famous and successful broker like "interactive brokers" which is valued at $26 Billion eventhough it handles less volume , has a lot less accounts signed up (see pdf) and is ranked only in the 13,000's on alexa VS binance in the 270's world most visited site , you realize that BNB token valuation (market cap) should be much higher obviously . And CME group they're valued at $52.6 B and they handle only $15.6 million a day.
BNB token issued by binance can be seen as shares. They burn tokens quarterly so the supply actually decreases. At the same time , they are adding thousands of new accounts everyday. As the cryptospace continues growing as more coins or token shares from companies are created , the volume should continue increasing , and so should the price of BNB.
Binance is also the 1st exchange by volume (eventhough sometimes a korean exchange with Korean Won pairs is ahead for the day) It's becomming a really big business , they are making millions everyday with fees. It's no wonder they are the top exchange. Everybody loves binance. Withdrawals are fast , orders are quick , prices are responsive , not static. Interface is professional but user friendly. The growth is steady.
