Bitcoin ETF Flows This Week: Friday’s $643M Exit Turns It Red

Bitcoin ETF flows were green for four days, then one day took it all back. US spot Bitcoin ETFs lost a net $643.2 million on Friday, October 30, their biggest single-day outflow since June and the first full trading day after the $6.36 billion Binance hack.

That turned the week from October 26 to 30 into a $202.4 million loss and closed October $515.9 million in the red. Ethereum ETFs lost money on all five days, $431.4 million in total, for a fifth losing week in a row. BTC trades at $77,054 at the time of writing. So was Friday a hack reaction, and does it change the picture?

Farside’s corrected Friday update has every fund’s number for the last three weeks:

How Did Bitcoin ETF Flows Turn Red This Week?

In one session. Monday to Thursday brought in $440.8 million, Farside’s data shows, enough to turn October positive by Wednesday. Friday’s exit was bigger than all four days together.

It is the second week in a row with a heavy end. Last Thursday and Friday took out $773.5 million, and Friday’s $643.2 million is even bigger than the $635.6 million day on October 22, which was itself the largest since late June. Last week the first three days still left the total green. This week they didn’t.

Was Friday’s Exit About the Binance Hack?

It was the first day that could show it. Thursday’s US session closed at 20:00 UTC, and wallets at Binance began draining at 20:05 UTC, per TRM Labs. So Friday, which closed at 4:00 p.m. in New York (20:00 UTC), is the first set of fund numbers with the hack in it.

ETF flows don’t come with reasons attached, so nobody can say how much of Friday was the hack. What the data does show is breadth. Five funds lost money at once, the same pattern as October 22, and no fund took money in. That looks more like broad selling than one big holder moving out.

The price backdrop didn’t help. BTC fell from $81,344 on Wednesday’s close to $77,992 on Thursday, its lowest close since September 17, and touched $76,326 on Friday. Binance withdrawals were still paused through Friday, with the exchange aiming to restart them by early Sunday.

Which Bitcoin ETFs Lost Money This Week?

Almost all of them, and mostly on Friday, when the Bitcoin ETF outflows came from five funds. BlackRock’s IBIT lost $233.7 million that day, Fidelity’s FBTC $201.0 million, ARK’s ARKB $129.5 million, Grayscale’s GBTC $53.3 million and Bitwise’s BITB $25.7 million.

Over the five days, the scorecard looks like this:

• IBIT: +$176.9 million, the only big fund still green for the week after taking in $410.6 million from Monday to Thursday.
• FBTC: −$166.0 million. Its $35 million from Tuesday and Thursday barely dented Friday’s exit.
• ARKB: −$129.5 million, all on Friday and bigger than its $109.4 million exit on October 22.
• GBTC: −$53.3 million; Grayscale’s smaller Bitcoin Mini Trust lost $15.3 million on Thursday.
• BITB −$15.6 million, BTCW −$3.8 million, Morgan Stanley’s MSBT +$4.2 million.

The pattern from last week holds. IBIT gets the dip buying, and the other funds take the exits.

Bitcoin ETFs Close October $516M in the Red

Friday was October’s last trading day, so the month’s Bitcoin ETF flows are final: US spot Bitcoin ETFs lost a net $515.9 million in October. October 1 to 16 lost $614.7 million, the week of October 19 got back $301.2 million, and this week gave $202.4 million away again.

By Wednesday the month stood about $110 million in the plus, so October flipped from green to red in two sessions. In price terms the month is just as weak: BTC opened October at $83,624, and the October close on Saturday decides whether it is a second red October in a row.

Ethereum ETF Outflows: Five Losing Weeks

Ethereum ETF outflows hit $155.7 million on Friday, the worst day of a week with no green days, per Farside. BlackRock’s ETHA lost $76.6 million, Grayscale’s mini fund $34.1 million, Grayscale’s ETHE $21.5 million and BlackRock’s staked Ethereum fund ETHB $19.5 million.

For the week, ETHA lost $391.1 million, about 90% of the group’s outflow. Fidelity’s FETH was the exception: it took in $63.1 million over the five days and only turned red on Friday. October ends with about $1.61 billion out of Ethereum ETFs, $1.42 billion of it from ETHA, and five straight losing weeks. ETH trades at $2,236, down 17% in 30 days.

Bitcoin Price Analysis: Can BTC Hold $76,264?

So far it has. The BTC price closed Friday at $77,369, and the day’s low of $76,326 stopped just above support at $76,264, the swing low from September 2. Fear & Greed reads 30, in fear.

• The ceiling: $81,479, the latest swing high, with the 50-day moving average right above it at $81,953.
• The floor to defend: $76,264. Friday tested it and held.
• The deeper support: $74,968, the September 15 low, then the 200-day moving average at $73,177, about 5% below the price.

In the bull case, Binance withdrawals restart without trouble, Monday’s ETF flows turn green again and BTC climbs back toward $81,479. In the base case, flows stay mixed and BTC chops between $76,264 and $81,479. In the bear case, a second big outflow day breaks $76,264 and opens the way to $74,968 and the 200-day.

TRAIL MAP: Support and Resistance in Plain English: Floors, Ceilings and Why They Work

Monday’s Bitcoin ETF flows are the next test. A week ago one heavy end still left the week green; this time it didn’t. If the dip buyers come back to IBIT after the weekend, Friday was a one-day reaction. If not, November starts the way October ended.
