Which stock exchanges have the biggest one-day percentage gains?

In the realm of cryptocurrency and finance, the question of which stock exchanges have witnessed the most significant one-day percentage gains is a pertinent one. Could you elaborate on the exchanges that have achieved remarkable surges in their daily trading? Specifically, I'm interested in understanding which platforms have witnessed double-digit or even triple-digit gains in a single trading day. Are there any patterns or trends that emerge from these outliers, such as a particular sector or type of asset that tends to experience such explosive growth? Furthermore, what factors contribute to such dramatic gains, and how do investors typically react to such volatility?
