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.
But where BNB coins go after used in IEOs? Do they go back in circulation (if yes then everytime after an IEO there will be a BNB dump)? Where can I find more informations on this?
