Confirmed, with a twist: big bitcoin holders are handing their coins to BlackRock’s spot bitcoin fund, IBIT, in exchange for shares. The viral version of the story got the tense wrong.

Watcher Guru posted at 13:57 UTC on Monday, November 9: “JUST IN: $15 trillion BlackRock expects billions of dollars in crypto to move into ETFs over security concerns.” The post linked no source. The story it was relaying is a Barron’s interview with Robbie Mitchnick, BlackRock’s head of digital assets — carried on Yahoo Finance and in full via Dow Jones syndication on Tiger Brokers — and that piece describes conversions that have already happened, not a forecast.

According to the Dow Jones syndication, BlackRock has seen $3.6 billion of in-kind conversions into IBIT since regulators approved them last year, and the real figure could be larger because BlackRock does not process every conversion itself. Mitchnick told Barron’s that “the current moment is the highest we’ve seen at any point,” and that of all the reasons clients give, “the single largest one is security and peace of mind.” The minimum swap size has fallen from about $30 million to between $1 million and $2 million.

One number does not line up. In August, Mitchnick told Bloomberg that IBIT had facilitated more than $5 billion of these swaps, as Yahoo Finance summarized. Bitcoin Magazine flags the same gap between that figure and Monday’s $3.6 billion. Neither outlet explains it, and several X accounts are quoting the bigger number as if it were new.

The bigger caveat is what an in-kind swap is. A holder delivers bitcoin and gets newly created fund shares. No bitcoin is bought on the open market, so the flow shows up in ETF figures without any new cash behind it, as Bitcoin Magazine points out. Meanwhile, Bitcoin Magazine cites Farside Investors data showing US spot bitcoin ETFs lost about $1.28 billion in the week ended November 6, with IBIT accounting for about $1.21 billion of it.

The security worry is real: Barron’s ties it to hacks like the recent Binance theft, and ForkLog carries the same account. The trade-off is just as real. A holder who converts gives up the private keys for a brokerage claim held by BlackRock’s custodian.
