I believe that many still underestimate the extent of the news of the commercial margin; when it will work the BnB token will reach other quotations than those given here, of $ 40 or $ 50, but it will come easily to $ 100, and in an upcoming bull run I would not be surprised to see peaks much, much higher.
Furthermore, with the introduction of the trading margin I believe that it will bring new life and strength to the whole market in general, starting with Bitcoin, Ethereum and Ripple.
They always have a big news to announce, and their competitors was not competing at the high level so people choose Binance over the others.
We know their news is big enough to cause a big surge so I will not be surprise if further increase would happen, and you are right, 100 usd is easy.
