Bitcoin (BTC) has surged past $78,000, propelling the broader cryptocurrency market upward. This move follows an improvement in risk sentiment after US President Donald Trump extended the ceasefire with Iran, alongside gains in stock index futures.

The cryptocurrency's ascent marks the end of weeks of volatile trading between $65,000 and $75,000, providing momentum traders with the catalyst they had been anticipating. Momentum traders typically buy when they see evidence of an upward trend, and Bitcoin's breakout serves as a clear signal, potentially attracting more buyers and amplifying momentum.

As a principle of motion states, an object in motion remains so until acted upon by an external force. Analysts at Marex noted, 'The market spent months capped between $65 and $75.

Breaking out of this range is significant because it changes behavior. Sellers who were previously comfortable selling rallies above $74 now need to reassess, while momentum buyers waiting for confirmation finally have a basis to act upon.' On-chain indicators also support this outlook, with the number of coins held in wallets tied to centralized exchanges dropping to a multi-year low of 2.67 million BTC, according to CryptoQuant, indicating continued investor accumulation that could lead to a supply shock. 'Bitcoin supply on exchanges continues to shrink, with fewer coins available for sale, more BTC moving to long-term holders, and liquidity tightening.

Bitcoin is becoming increasingly scarce – reduced supply means increased volatility,' Delta Exchange stated. However, QCP Capital advises caution, pointing to the persistent relative richness of bitcoin put options on Deribit, which are used as a hedge against potential price drops. The firm notes that crypto trends are currently tied to the price of oil and the interest-rate outlook.

'The path forward remains tied to oil and policy. A move lower in crude or clearer Fed signaling would support risk, but without this, markets are likely to remain in a holding pattern, pricing uncertainty rather than resolution,' QCP Capital said in a market update. In traditional markets, WTI crude futures are trading around $90, having rebounded from a low of $78 on Friday.

The broader market continues to face DeFi security risks as hacks escalate. The Sui-based Volo protocol was recently drained of over $3 million, just days after the KelpDAO incident caused collateral damage across the sector.

The chart illustrates bitcoin's daily price movements, with lines indicating the 100-day and 200-day average prices.

Bitcoin's price has established a firm foothold above the 100-day average, which is pivotal as it previously capped the bounce in January, leading to a deeper crash. Now that the price has pierced through, it typically signals a strengthening of bullish momentum, with the focus shifting to the 200-day average, currently at $85,900.
