Bitcoin's (BTC) 30-day implied or expected volatility index, BVIV, jumped by nearly 22% in June, the first monthly rise since February, according to data source Volmex.
The upswing happened as the spot price dropped by 20% to under $60,000.
BTC's volatility index has developed an inverse correlation with the spot price since at least 2024, signaling Wall Street–like dynamics where the VIX moves in the opposite direction of the S&P 500.
The BVIV, therefore, could be called a BTC "fear index," much like the VIX.
Tokenized stock lending protocol Edel Finance halted its smart contracts after an attacker exploited an oracle pricing flaw involving wrapped tokenized stock collateral, creating about $403,000 in bad debt.
According to the protocol, the attacker manipulated the exchange rate between the wrapped tokenized stock of Google’s parent company Alphabet, wGOOGLx and the unwrapped version, GOOGLx, causing wGOOGLx collateral to be valued at roughly 78 times its correct value before borrowing against it.
Edel advised users not to interact with the protocol. The team said it will absorb the bad debt and restore affected depositors' balances 1:1.
The exploit is among the first publicly disclosed attacks involving a lending protocol built around tokenized equities. Edel said it will release a full technical post-mortem after its investigation.
U.S. spot bitcoin ETFs recorded $4.5 billion in net outflows in June, their worst month since launching in January 2024, per SoSoValue data.
The previous record was $3.48 billion in February 2025. June's figure beat that by 29%.
BlackRock's IBIT, the largest fund by assets, accounted for $3.55 billion of the monthly total alone, including $212 million on June 30, the ninth consecutive day of net outflows. Total ETF assets have fallen to about $71 billion from roughly $83 billion at the start of the month.
Two events may have set the streak in motion. SpaceX debuted June 12 and within days had absorbed billions in risk capital, with retail buying on its first trading day breaking all single-session records and the offering raising $75 billion in total.
