Spot Bitcoin ETFs Post Strongest Weekly Inflows Since April After Coldcard Hack
US-listed spot Bitcoin ETFs saw net inflows of about $853.5 million over the past five days, the strongest weekly performance since mid-April, according to SoSoValue. Inflows peaked at $244.42 million last Wednesday. The move follows a Coldcard hardware wallet hack tied to Coinkite’s Coldcard vulnerability, estimated at about $130 million stolen. Spot Ethereum ETFs added about $245 million weekly inflows.

Why it matters
Quantified ETF inflows (BTC and ETH) provide a near-term positioning signal for traders monitoring regulated crypto access and custody-related sentiment.
Market read
Spot Bitcoin ETFs posted their strongest weekly inflows since mid-April, while spot Ethereum ETFs also saw sizable inflows, both framed as sentiment shifts after a custody hack.
What to watch
The article does not quantify outflows from other crypto products or broader risk-off drivers that could overwhelm flow support.
Background
The piece attributes renewed spot Bitcoin ETF demand to concerns sparked by a Coldcard hardware wallet vulnerability exploited by attackers.
Ticker impact
Spot Bitcoin ETFs saw $853.5M net inflows over five days, with the Coldcard self-custody hack cited as renewed demand catalyst.
Mildly bullish near-term bias for BTC given sustained ETF inflows, with volatility risk if hack-related concerns fade or reverse.
The article provides quantified inflow streak data and links it to the Coldcard hack narrative, which can support flows for days to weeks.
Spot Ethereum ETFs recorded about $245M weekly inflows, alongside commentary that ETH is targeting reclaim of the $2k resistance level.
Moderately bullish short-term bias for ETH if inflows persist, with upside contingent on follow-through toward $2k.
The text includes inflow figures and a resistance-level thesis, but no new Ethereum-specific fundamental event is disclosed.
Market effects
Stronger spot-ETF flows can lift broader crypto sentiment, especially for assets viewed as ETF proxies or altcoin barometers.
US-listed ETF flow data can influence global crypto liquidity and derivatives positioning.
Coldcard hack narrative may shift global investor preference toward regulated custody structures, affecting cross-exchange demand.
Counterpoint
ETF inflows may be transient, driven by short-lived security headlines rather than durable allocation changes.
