Sats vs Bitcoin is like comparing drops of water to pools of water. It’s all water. Now Lightning on the other hand is a separate currency. It’s a layer 2 protocol built on top of the blockchain.
Think of it like using chips at a casino instead of cash even though you still refer to the chips as dollars since they can be easily traded back and forth.
Same thing with the Lightning network where people refer to the payments as Sats, but we know it’s actually Lightning currency.
