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.
I think the role of the IEO they are doing for marketing sales from the new project is one of the best weapons to continue to increase their value. the more people turn to the IEO they do, the higher the demand for the BNB. and that's very good.
That's very good for us investors, however we should also look on exchanges that offers IEO.
It cannot be BNB alone to rule the market, they have the most popular IEO but sooner these big exchanges will compete and will also host a great project in IEO. I am also thinking possibilities that one project can be hosted in different exchanges for its IEO, that would help the sale
as people does not only trust Binance for the IEO.
