After the Bitcoin price crash, its application and acceptance in the cross - border payment field may be affected. Merchants and users may become more cautious about using Bitcoin for cross - border payments due to its price volatility. The value of Bitcoin as a payment method may decline in the short - term as its price stability, which is crucial for payment applications, is undermined. However, in the long - term, if Bitcoin can regain stability and its underlying technology continues to improve in terms of transaction speed and cost - effectiveness, its application and acceptance in cross - border payments may still recover.
