Binance plans to distribute 7% of the total PIXEL token supply to users on Launchpool. This translates to 350 million PIXEL tokens out of a total supply of 7 billion tokens.
80% of these rewards will be distributed to BNB stakers, while the FDUSD pool will receive 20% of the rewards. However, this doesn’t necessarily mean that you will earn more PIXEL if you stake BNB rather than FDUSD. It all depends on how big the size of your stake is relative to the size of the staking pool you've selected.
