Let's say you start with 1,000 RUNE, and RUNE is worth $1.You sell 500 rune in order to buy 20 BNB at $25.You now enter a RUNE:BNB pool where you hold 50% RUNE and 50% BNB.RUNE price increases 2x, and you ask "Why do I not have $2,000 worth of RUNE total?" (your original 1,000 RUNE).Remember, you sold half of your RUNE. You are now only 50% exposed to RUNE. Your pool share is now worth $1,500 (a 50% gain compared to holding 100% RUNE)You now have ~350 RUNE (-150) and ~28 BNB (+8), because the pool balanced itself out. This is 750 RUNE total if you were to withdraw and swap your BNB back to RUNE.If you want to HODL 100% RUNE, do not use BEPSwap to provide liquidity. Because you will need to sell half of it to buy the other asset.
