Also, don't forget to create a Short counterpart on BNB so that price fluctuations won't bite you back.
$BIO Protocol will have a stock of 3.32 Billion Tokens, with a few more than a Billion released at the end of the launch pool. From these numbers, we can expect the price of BIO to sit around $0.5~3 per coin.
After a quick math, and considering the amount of BNB Locked will increase to 20 Million; you should be getting about 5~9 BIO tokens per BNB stacked.
Happy farming!
