Bitcoin's price fell to its 50-day simple moving average (SMA) at $103,150, extending 24-hour losses to 4.59%, according to CoinDesk data. Prices briefly topped the $110,000 mark early this week. The bulls might be hoping for the 50-day SMA to hold, as a potential decline below it could entice more sellers, as observed after the support broke down in February.

The per-barrel price of WTI crude surged over 6% to $74.30 per barrel, reaching the highest since Feb 3, and extending the weekly gain to 13%, according to data source TradingView. The move happened after Israel conducted airstrikes on Iran, supposedly drawing retaliatory missile action from Tehran.
