‘Buy the rumor, sell the news’ — Bitcoin ETF may spark TradFi sell-off

Bitcoin may suffer when the United States approves the first spot exchange-traded fund (ETF), a new warning says.

In a thread on X (formerly Twitter) on Nov. 28, Joshua Lim, head of derivatives at capital market firm Genesis Trading, predicted a volatile start to 2024 for BTC price action.

Bitcoin ETF approval: Retail may be left holding the buck

Lim said that Bitcoin is already a target for traditional finance, or “TradFi,” which is betting on winning big out of the spot ETF approval.

“We know tradfi guys / macro tourists are already long crypto ahead of ETF news. They’ve built the position over the last few months and are now paying handsomely to roll it,” the thread explained alongside data covering open interest on CME Group’s Bitcoin futures.

“Commitment of traders data showing asset managers increased length by about $1bn since end of Sep.”

The signs are there in the performance of the first Bitcoin futures ETF (BITO), as well as stocks of crypto firms such as U.S. exchange Coinbase (COIN), the latter up 250% year-to-date.

While generating buzz and emboldening the institutional adoption narrative behind Bitcoin, the party could quickly fizzle once the spot ETF is given the green light. This, Lim and others suggest, would be a classic “buy the rumor, sell the news” event.

“What does it all mean?” he queried.

“Tradfi is already long and probably thinking about when to exit this trade around etf announcement expect retail to pile in.. and expect tradfi guys to exit (2021 tops in basis were prior to COIN and BITO listings).”

A gold ETF rerun?

Lim is not alone in wondering if ETF approval day will ultimately leave lay investors disadvantaged.

Responding, James Straten, research and data analyst at crypto insights firm CryptoSlate, channeled history to support the concerns.

“When the Gold ETF (GLD) was introduced in November 2004, it opened around $45 and dropped to approximately $41 by May 2005. However, it saw an impressive 268% increase over the subsequent seven years,” he added in a CryptoSlate analysis on Nov. 28.

On a more optimistic interim note, popular trader Jelle remarked that institutional interest had not been dented by the week’s news stories, including the $4.3-billion settlement between the U.S. government and the largest global crypto exchange, Binance.

CME futures, he stressed, continue to trade at a premium over the Bitcoin spot price.

    We propose the Collusion-Resistant Impartial Selection Protocol (CRISP) to improve on MACI’s honest Coordinator assumption.

We propose to increase the trust model further by introducing economic disincentives for compromised Coordinators.

  • Multiple incidents of stETH being stolen and cross-chained to the Blast mainnet were discovered. The victim’s mnemonic words/private keys may have been leaked.

    SlowMist founder, Yu Xian, posted on X platform stating that SlowMist and MistTrack have received at least four cases of stETH being stolen and cross-chain transferred to the Blast mainnet. The common feature is that a small amount of ETH transaction fee is sent from an address with obvious traces (including exchanges) to the stolen address, and then stETH is cross-chain transferred to the Blast mainnet for subsequent transfer, and finally the remaining small amount of ETH in the victim's address is transferred to different ETH addresses. The known loss exceeds 100 stETH, and it is likely a group event. The mnemonic phrase/private key of these victims must have been leaked, and the attackers lurked to start on the Blast mainnet. Previously, Scam Sniffer monitoring showed that a certain address lost over 10 BTC pledged on Aave and some PANDORA due to interaction (clicking on the signature authorization) with a fake Blast airdrop website, with a total loss of approximately $717,817.
