The success of Binance Launchpool lies in its massive user base of over 200 million. This means a project conducting an IEO on Binance will be promoted to 200 million crypto investors who are already active in the market, not just random potential investors.
Launchpool also positively impacts BNB price by increasing the demand for and holding of BNB in the short term, helping BNB escape negative price patterns and recover quite quickly over time. During this bullrun, new launchpools and the price increase of those tokens will have an even more positive impact on the growth of Binance CEX and BNB price in the market. The model CZ built is truly brilliant!
At least when the launchpool is on Binance, the price of that coin will usually rise quickly and have a good value at the beginning, although it is unclear whether it will grow in the future or not, or whether it will survive or not. However, usually, the launchpool will bring success to the altcoin that was won at the beginning.
And for BNB, yes, it is undeniable that if you hold BNB on Binance, it is indeed one way to take advantage of this launchpool program. It's just that the results will depend on the BNB we have. But this is indeed one of the factors to increase the BNB use case and make us hold BNB as much as possible on the exchange.
