When Bitcoin's price breaks below a key support level, predicting the next support is challenging. Some analysts suggest that the next support might be around $73,800 based on historical data and technical analysis. 

Factors potentially triggering a bottom - bounce include positive regulatory news, like the approval of new Bitcoin - related financial products. If more institutional investors enter the market due to improved regulations, it could drive up demand. Also, a change in global economic sentiment, for example, if major economies show signs of recovery, might make Bitcoin more appealing as a store - of - value asset, thus pushing its price back up.
