16.384 bnb hard cap per user
That's the maximum allocation a user can get of; doesn't necessarily mean you will get 16.384 BNB allocation if you hold 16.384 BNB. There are people with thousands of BNB, their allocation must be higher than you. That's how Binance designed the launchpad. The more BNB you hold, the more allocation you get.
Now I still have no idea what this is about, but it sounds like Binance is using their own centrally controlled made-up coin to hype another made-up token. Why did people "commit" 5 billion dollars (in Binance's centralized coin) to this?
It's Binance Launchpad aka ICO. FC Porto has launched their ICO through Binance Launchpad; anyone can participate with holding BNB but holding 1 or 2 BNB for a week will only get you 5/6 PORTO coins.
I see a hype that reminds me of the peak of the ICO, but I'm not sure what you're getting at. Can you start by not using a "dot" for thousands and for decimals? It's quite confusing to read now.
OP doesn't know how it works. As I said above, the maximum investment an individual can do is 16.384 BNB regardless of how much (I mean high) BNB they hold. If I'm correct, there's an explanation of who got how much.
