According to Cointelegraph, as trading volume increases, the issuer of the US Bitcoin spot ETF has added a net 10,667 bitcoins on the fifth trading day. Data compiled by CC15Capital on January 17th shows that their net holdings of bitcoin increased by $440 million at the close of that day. BlackRock's ETF accounted for the majority, with a net increase of 8,700 BTC worth nearly $358 million.
The data also shows that nine ETFs (excluding Grayscale) have purchased nearly 68,500 BTC since their launch, currently valued at approximately $2.8 billion. The bitcoin purchases associated with ETFs were partially offset by outflows from Grayscale Bitcoin Trust Fund (GBTC), which sold 10,824 BTC worth about $445 million. Since GBTC converted to a spot ETF on January 11th, almost 38,000 BTC have flowed out.
Meanwhile, data shared by Bloomberg ETF analyst Eric Balchunas shows that daily trading volume for spot Bitcoin ETFs other than GBTC surged by 34% as of the fifth trading day.
