US spot Bitcoin ETFs posted $180 million in net inflows on March 13, according to SoSoValue, pointing to stronger institutional participation in regulated crypto investment products. BTC traded near $72,000 during the move, while total crypto market capitalization also climbed, reflecting firmer interest in listed vehicles tied to digital assets.
BlackRock's IBIT logged five straight sessions of inflows
BlackRock's iShares Bitcoin Trust was the clearest driver in the latest stretch. The fund recorded inflows for five consecutive sessions: $144 million on March 13, $46.15 million on March 12, $115 million on March 11, $185 million on March 10, and $109 million on March 9. The sequence shows continued use of exchange-traded funds by professional investors seeking BTC exposure through regulated products rather than direct holdings.
The weekly figures also moved higher. The previous week's inflows totaled $568 million, while the current week reached about $767 million, an increase of more than $200 million. That rise came as prices improved and sentiment strengthened, keeping Bitcoin ETFs at the center of institutional allocation activity.
Ethereum spot funds extended a four-day positive run
Demand was not limited to Bitcoin. Ethereum-focused spot funds recorded $26.69 million in total inflows, extending their positive streak to four days. iShares Ethereum Trust led that move with a $32.39 million single-day addition, making it the main contributor among ETH-linked products mentioned in the source material.
The flow pattern suggests that some investors are broadening crypto exposure while staying inside regulated market structures. Alongside new funding rounds and product launches cited in the source, Ethereum funds are becoming a larger part of institutional portfolio construction.
BlackRock's staking ETF ETHB drew $115 million on day one
A separate milestone came with the launch of BlackRock's staking-focused exchange-traded fund, ETHB. On its first day, the product attracted $115 million in investments. The source described this as a sign of rising appetite for yield-oriented blockchain products offered within compliant investment frameworks.
From the $180 million daily intake for spot Bitcoin ETFs to steady inflows into Ethereum funds and the strong opening for ETHB, regulated digital-asset products continue to gather capital. Current flow data shows institutions concentrating on listed vehicles that offer structured access to crypto markets.
