Bitcoin continues to face downward pressure, failing to hold the $68,000 level, with the decline widening. It has fallen 1.7% in the past 24 hours and 7% over the week. Analysts believe that the weakness in Bitcoin is due to broader geopolitical tensions intensifying risk aversion, as well as concerns that future quantum computing could pose a threat to Bitcoin's encryption. Although the current bearish momentum is strong, some forecasts indicate that if market conditions stabilize, Bitcoin could rebound to around $78,500 in early April.
