You forgot to deduct one detail in order to buy coins during the sale. Chris needed to use scripts (early sales on Binance) or to have 30 BNB on the balance sheet, which is a significant amount, with a chance to win a ticket in the lottery about 30%. So it's not that simple.
yes, indeed that is what must be done, to follow the IEO at binance we must have a BNB in our account to be exchanged for tickets in the IEO sale. it makes the IEO limited to only a few members, communities that win a lot of each other, and that makes buying prices on the market when opened for trade very crowded.
