#MarketBuyOrHold? Regulatory changes significantly influence cryptocurrency bull runs by shaping market sentiment and investor confidence. Positive developments, such as the approval of Bitcoin exchange-traded funds (ETFs), provide institutional investors with a regulated avenue for participation, leading to increased demand and price surges [1][3].

Conversely, negative regulatory news can trigger sell-offs and market corrections, highlighting the delicate balance between regulation and market dynamics.
