According to Cointelegraph, major Bitcoin treasury companies purchased over 6,702 Bitcoins last week, investing approximately $1.2 billion. Japan's Metaplanet increased its holdings by 5,258 Bitcoins in a single week. However, the key driver of Bitcoin's price exceeding $125,000 came from spot Bitcoin ETFs, which saw net inflows of $3.24 billion in a single week, nearly matching the previous weekly record set in November 2024. Furthermore, institutional buying of Bitcoin has far outpaced miner output this year. According to an analysis by financial services firm River, companies are purchasing an average of 1,755 Bitcoins per day, while ETFs absorb an average of 1,430 Bitcoins per day, while miners produce an average of approximately 900 BTC per day. Several analysts have pointed out that the inflow of ETF funds, combined with tight liquidity, could further amplify Bitcoin's volatility and potential for growth.
