Bitcoin fell back below the $78,000 level after running into resistance at $80,000.

CoinDesk, a blockchain media outlet, reported on April 27 that bitcoin briefly rose above $79,000 during Asian trading hours but later gave up gains. It is down about 2 percent over the past 24 hours.

Markets see a concentration of sell orders around the $80,000 area as creating a near-term ceiling. Alex Kuptsikevich, chief market analyst at FxPro, said bitcoin approached $80,000 for a second time in recent days but selling pressure then intensified. He said sell orders piled up at that price level are preventing further gains.

Still, views remain limited that the pullback will lead to a trend reversal. Kuptsikevich assessed that this retreat looks like a temporary move within a larger uptrend that began in late March. It indicates that while bitcoin hit resistance in the short term, medium- to long-term fund flows remain supportive.

On-chain data and exchange-traded fund (ETF) flows also supported that view. CryptoQuant data showed net inflows of about $3.4 billion in stablecoins into Binance so far this month. That follows net inflows of $3.0 billion in March, indicating continued inflows. CryptoQuant analyst Darkfost explained on X, formerly Twitter, saying, "This shows new funds are flowing in to participate in the recovery phase."

Institutional demand is also holding up. U.S.-listed spot bitcoin ETFs have taken in $2.44 billion this month. That is the biggest amount since October last year, when bitcoin topped $126,000 and set an all-time high (ATH). With inflows through spot ETFs continuing while bitcoin has failed to break through its short-term resistance, the market is focusing on a lag between supply-demand dynamics and price.

Risk factors remain. DeFi security-related risks continue to weigh on investor sentiment. Last week, Sui (SUI)-based lending platform Scallop was attacked and lost about 150,000 SUI, worth about $142,000. The loss was not large, but it added to attack cases after hacks at Drift and KelpDAO earlier this month.

Memento Research said DeFi protocols lost about $623 million to hacks in April alone. Cumulative losses, compiled by DeFiLlama, stand at about $7.72 billion. It indicates DeFi security vulnerabilities remain a structural risk.

By type of attack, private key theft accounted for the largest share. Private key leaks made up 40 percent of total losses. Because private keys are core authentication information that controls cryptocurrency wallets, once stolen it is effectively difficult to recover the wallet and funds. That has prompted calls for security checks to expand beyond smart contract vulnerabilities to include private key management systems.

Traditional financial market variables are also in play. West Texas Intermediate (WTI) crude is trading above $90 a barrel and Brent crude above $100. With supply constraints continuing, higher oil prices could stoke concerns about inflation and global economic instability, potentially affecting risk appetite in crypto markets. The near-term focus is whether bitcoin will test $80,000 resistance again or whether external variables and DeFi risks will deepen the pullback.
