BTC Falls 3.89% This Week: Only 40 of 200 Weeks Were Weaker
Robinhood added bitcoin, yet BTCUSDT still closed the week down 3.89%, ranking 160th out of 200 weekly samples.

The news landed, and price answered the other way
Robinhood added bitcoin, a headline that circulated widely. In the same week, the Binance BTCUSDT perpetual contract moved from 86482.8 USDT on 2026-10-05 to 83120 USDT, a weekly decline of 3.89%. Placed against a 200-week sample, that ranks 160th, in the back half of the sample, with 159 weeks stronger. A buyer acting and price falling can both be true. For contract traders, what matters is where each daily close landed and whether related symbols moved together.
Where each day closed
The table below covers BTCUSDT perpetual daily data from 2026-09-30 to 2026-10-07, with open, close and change taken directly from the interface.
| Date | open (USDT) | close (USDT) | Change |
|---|---|---|---|
| 2026-09-30 | 83624.5 | 83576.9 | -0.06% |
| 2026-10-01 | 83576.8 | 84829.6 | 1.5% |
| 2026-10-02 | 84829.6 | 84482.8 | -0.41% |
| 2026-10-03 | 84482.7 | 84710.6 | 0.27% |
| 2026-10-04 | 84710.5 | 86482.8 | 2.09% |
| 2026-10-05 | 86482.8 | 85717.2 | -0.89% |
| 2026-10-06 | 85717.2 | 85507.5 | -0.24% |
| 2026-10-07 | 85507.6 | 83120 | -2.79% |
Three days stand out. On 2026-10-04 the close was 86482.8 USDT, up 2.09%, the only solid green day in the stretch and the source of the weekly open. On 2026-10-07 price fell from 85507.6 USDT to 83120 USDT, down 2.79% in one day, giving back the earlier gains. In between, 2026-10-05 closed at 85717.2 USDT, down 0.89%, and 2026-10-06 closed at 85507.5 USDT, down 0.24%. Adding the 1.5% on 2026-10-01 and the 2.09% on 2026-10-04 still does not offset the single 2.79% drop on 2026-10-07, which is why the week closed at 83120 USDT.
The 200-week context
A 3.89% weekly decline ranks 160th out of 200 weeks, in the back half of the sample, with 159 weeks stronger. For reference, several weaker weeks in the data can be listed side by side: the week of 2023-01-30 fell 3.42%, the week of 2025-05-26 fell 3.1%, the week of 2025-08-18 fell 3.33%, and the week of 2025-10-27 fell 3.5%. All of those declines are smaller than this week's 3.89%, so they rank ahead. On the other side, the week of 2023-01-09 rose 21.95%, the week of 2023-03-13 rose 27.15%, the week of 2024-02-26 rose 22.05%, and the week of 2026-08-17 rose 23.61%. A single-week 3.89% decline sits in the weaker band of 200 weeks, but far from the worst.
What the trending posts say
Trending posts on Square argue that Robinhood adding bitcoin signals institutions continuing to put bitcoin on their balance sheets, supportive for crypto-equity and bitcoin contract sentiment (relayed, not the view of this site). Some in the same discussion focus on HOODUSDT, COINUSDT and MSTRUSDT, the US-equity USDT-margined perpetual contracts, arguing the news shows up in equities first and then transmits to bitcoin itself. Those claims offer an angle, but they describe expectations, not realized prices. This week HOODUSDT moved from 114.63 USDT to 108.77 USDT, down 5.11%; COINUSDT moved from 186.85 USDT to 178.11 USDT, down 4.68%; MSTRUSDT moved from 164.84 USDT to 153.63 USDT, down 6.8%. All three weekly directions match BTCUSDT.
Three things to think through first
First, news and price live on different time scales. Adding bitcoin is a completed action, while a weekly close is the sum of countless trades, and the two can diverge for a long time. Translating a headline directly into a direction skips every step in between.
Second, US-equity USDT-margined perpetual contracts and crypto USDT-margined perpetual contracts differ in trading calendar and liquidity structure. HOODUSDT, COINUSDT and MSTRUSDT listed on 2026-02-02, 2026-02-09 and 2026-02-09, far shorter than BTCUSDT's 2019-09-08, with weekly samples of 36, 35 and 35 weeks. Long-horizon comparisons should account for that.
Third, high leverage turns a survivable swing into a forced exit. Within the move from 86482.8 USDT to 83120 USDT, 2026-10-07 fell 2.79% in a single day, enough to trigger passive deleveraging in a high-leverage position. Funding fees also accrue, so holding time carries cost. The idea that the best week is only obvious in hindsight applies here too: the week of 2026-08-17 rose 23.61%, and nobody knew at the time it would be one of the sample's highs.
Trading costs this week
The Binance contract default maker fee is 0.02% and the default taker fee is 0.05%. The rebate ratio is 20%, leaving an effective maker fee of 0.016% and an effective taker fee of 0.04% after the rebate. For anyone trading in and out frequently within a week, the taker side accumulates more visibly than the maker side, and it belongs in the P&L calculation.
