Some project teams raised 1500 BNB in private placements, while others raised 150 BNB. Participating with the same amount of BNB in the new offerings, of course, the later oversubscription is ten times that of the earlier ones.
The correct calculation is to see how many BNB in total participated, divide the number of tokens from the project team by the total number of participating BNB, and then multiply by the BNB amount you participated with, which gives you the number of tokens you can receive.
If this token goes directly to Binance's spot market, its market value would be around 50 million USD. If it only goes to Alpha, its market value would be around 15 million USD. Divide the market value by the total supply to get the price per token, then multiply by the number of tokens you receive, that’s your share. It's not about how many times it oversubscribes, use your brain a bit.
