Always before a launchpool bnb goes up and then goes down again As soon as it's over. I've been buying and selling for a year with a decent profit

Good evening! I need someone to help me with some reasoning here!

When the BIO launchpool ends and users withdraw their more than 18 million BNB from there, (this amount being approximately $12,830,000.00 or 12.83 billion US dollars) and a portion ≈ 5% of this amount is sold (≈ 900M BNB / ≈ 691.5M USD) with the market capitalization of BNB being ≈ 102.8 billion this sale would represent ≈ 0.67% of the total capitalization. It would be crazy to think that if this happened the price of BNB could have a variation of up to 1% or more downwards right after the end of the launchpool.

It may not seem like much, but if this happens, good positioning could generate a lot of money for me. Tell me if you think this could happen or if there is any other important point that I didn't take into consideration. I did some quick calculations in my head and came to this conclusion. Tell me what you think.

I believe that in 4 days, BNB will rise to around $740.00. If it reaches this value in a hypothetical situation and you had at least $1,000.00 in BNB, how many fractions would you sell?
