I usually buy after I finished the IEO, and sell it when there is an increase before the IEO starts and there is already a sales launchpad project. in a short period of time, short-term BNB trading can take advantage of that moment, where when there is an IEO, demand will increase.
With current conditions for the IEO participation on the Binance volatility can be less then usually. Closest IEO need to hold due to 7 days. But after it will be month. And we will see either daytrade volatility or BNB will become stable
