Nearly $900 million flowed out of Bitcoin spot ETFs, mainly due to outflows from the high management fee Grayscale, as well as a slowdown in subscriptions to related products from BlackRock and Fidelity.Last week's significant outflows triggered more hedging by traders against price declines, as well as a large number of leveraged long positions in the cryptocurrency futures market being closed.According to Goldman Sachs data, in the futures market, the number of open Bitcoin contracts hit a new high, exceeding 33,000 contracts with a nominal value of nearly $12 billion. The number of contract holders also approached a record high. Goldman Sachs also noted that during the week of March 5th to 12th, institutions were net buyers, with a scale exceeding 3 standard deviations, while hedge funds or leveraged investors were net sellers, with a scale also exceeding 3 standard deviations. Institutional net long positions and hedge fund net short positions are at record levels, and the concentration of long positions is also significantly higher than the average level.The mysterious buyer known as &#34;Bitcoin Whale&#34; and &#34;Mr. 100&#34; made another move.
