The cryptocurrency market has witnessed significant activity involving Bitcoin ETFs and whale transactions. Notably, BlackRock and Fidelity purchased a combined total of 4300 BTC, valued at approximately $297.3 million, marking the first net inflow for Bitcoin ETFs after a week of outflows. This comes amid a backdrop of the fifth largest Bitcoin whale, identified as '37X', reactivating after years of dormancy by moving $6 billion worth of Bitcoin, almost the entire balance of 94.5K BTC ($6.05B), to three new addresses. The '37X' wallet, which had not been moved since its accumulation since 2019, was involved in this significant transaction. This activity coincides with a period of volatility for Bitcoin ETFs, which experienced their first week of outflows after seven consecutive weeks of inflows, mainly due to drying up inflows from BlackRock & Fidelity, while Grayscale faced high outflows. The cryptocurrency market also saw a record weekly outflow of $942 million from digital asset investment products, ending a seven-week streak of inflows. Despite these outflows, the price of Bitcoin rallied back above $70,000, with investors seemingly unfazed by the recent ETF outflows.
