I just saw news about the Lighter derivatives platform - the Bitcoin price there suddenly dropped to $47,510 due to very low liquidity. This event was caused by a large whale who directly pushed 1,000 BTC through the exchange's order book.

In fact, this is related to the so-called cap wall or maximum price limit on the platform - when liquidity is insufficient, prices can be pushed up or down very sharply. That’s why understanding what a cap wall is is important for traders, as it directly affects price stability.

Lighter officials later explained that this was a technical issue caused by limited liquidity. It reminds me that on smaller exchanges, such price swings can happen quickly, especially when there is high trading volume.
