Institutional investors just bought an overall total of $1 billion in Bitcoin and crypto assets in one week, according to a new update from Coinshares.

The inflows mark a reversal from a five-week streak of outflows totaling $4 billion.

Bitcoin dominated the buying, drawing $881 million. Ethereum followed with $117 million in inflows, marking its strongest week since mid-January. Among altcoins, Solana led with $53.8 million.

The rebound was broad-based geographically. The US accounted for the bulk at $957 million, Canada saw $34.1 million, Germany $31.7 million and Switzerland $28.4 million.

CoinShares attributes the shift to recent price weakness and breaks below key technical levels, with renewed accumulation by large Bitcoin holders also playing a role.

Despite the surge, both Bitcoin and Ethereum investment products remain in net outflow positions year-to-date. Solana stands out positively with $156 million in YTD inflows.
