A $2.6B ETF Week Lands the Same Morning the First Longs Get Liquidated

The rally's receipt and its bill arrived on the same Saturday morning. Flow trackers published the weekly ETF numbers: $2.61 billion of combined net inflows into U.S. spot bitcoin and ether funds for the week ended 21 August, the best combined week since October 2025. Hours earlier, at about 04:00 UTC, bitcoin had flash-crashed out of the $79,000s to below $77,000. For the first time since the move began, the liquidation tape belonged to the longs.

The best flow week since October 2025

The headline figure moves a little by tracker. Crypto.news put the combined week at $2.61 billion, against $2.615 billion in KuCoin's flash; The Block rounded to $2.6 billion. All three agree on the ranking, and the gaps are rounding, not dispute. The week before, the same funds had bled $391.96 million. This time every one of the five sessions was positive for both categories, with bitcoin funds taking $1.92 billion and ether funds $697.47 million, each category's best weekly result of 2026.

Friday's session alone added $492 million, and BlackRock took most of it. IBIT drew $239 million, about 78 percent of the day's bitcoin inflows, while ETHA's $151 million was roughly 82 percent of the ether side. Combined ETF trading volume tripled to $29 billion from $8.8 billion the prior week, per The Block's Saturday write-up. The demand followed the squeeze that carried bitcoin through $72,000 on Wednesday and kept building into the close.

The first long-side flush of the move

The crash accounts differ on depth. COINOTAG had bitcoin dropping suddenly shortly after 04:00 UTC to below $77,000 before steadying near $77,260, and described a textbook liquidation cascade after an overextended rally. BeInCrypto's version ran from $79,500 to $76,300 and erased roughly $500 million in longs. The two low prints do not reconcile. What both accounts show is the flip: the cascade's peak hour liquidated about $523 million, and 86 percent of it was long positions, per CoinGlass data carried by COINOTAG. Through 19 to 21 August that tape had run 85 to 92 percent shorts.

The 24-hour totals disagree as well. COINOTAG counted $1.801 billion across 286,130 traders, while a CoinGlass snapshot carried by KuCoin put it at $1.675 billion across 283,359 traders, split almost evenly between sides. Neither pair of figures reconciles. The sources do agree on one number. The largest single liquidation was a $24.96 million bitcoin position on Hyperliquid.

Still negative for the year

The counterweight sits in the yearly ledger. Even after the strongest week in ten months, The Block's tallies show bitcoin ETFs about $2.9 billion net-negative for 2026 and ether ETFs down roughly $191.8 million. One heavy week has not repaired the year. A research caution quoted by crypto.news made the point directly:

"Sustained inflows are unlikely without additional confirmation. Until those catalysts develop, inflows will likely remain temporary rather than structural."

What has to hold from here

Bitcoin spent the rest of Saturday in a $76,900 to $77,300 band, still up about 22 percent on the week; KuCoin's snapshot read $76,902.20. BeInCrypto flagged the four-hour relative strength index, a momentum gauge, above 80 for the first time in seven years, a measure of how stretched the move had become. Ether printed $2,420.39 early Saturday after Friday's $2,448 high, extending the four-day run to a four-month high; a COINOTAG piece datelined around the Friday-to-Saturday boundary put later prints near $2,397, a figure we could not confirm elsewhere. The analyst split in BeInCrypto's survey is clean. Bulls target $83,000 to $88,000 if the $75,000 to $76,000 zone holds, and bears see $70,000 to $72,000 on the overbought extreme. One analyst called the reading good for the long term, but not for the short term.
