Own the future of agriculture robotics

Find out why the biggest food companies are quietly investing in this herbicide-free tech. 

Greenfield Robotics is building a new category of agricultural equipment: autonomous robots designed to help farmers manage weeds with precision.

What does “autonomous” mean? Greenfield’s robots are built to navigate fields, identify weeds, and perform targeted weed removal with minimal human intervention.

But the bigger opportunity may be the platform itself. It raises a bigger question: if robots can autonomously manage weeds, what other farm tasks could they eventually take on?

Greenfield is already expanding the platform beyond weeding, with feeding, spraying, and cover-crop planting on the roadmap.

The vision: a new generation of farm equipment that can perform more work autonomously—potentially reducing dependence on chemical inputs and the rising costs associated with conventional farming.

Investors can own a stake in Greenfield Robotics through its Regulation A+ offering. Up to 20% bonus shares this round.

Stocks had a rough Friday. Bitcoin had a quiet one

Pro Swing Trader Daily Brief
Saturday, October 17, 2026

Good morning.

Quick quiz.

On Friday, the Nasdaq lost more than 2%. Chip stocks fell for the eighth day in a row, the longest streak since 2008. Oil jumped 3.6% to about $110 a barrel, its highest since May.

So how far did Bitcoin fall?

0.8%. It closed at $81,500 after swinging between $80,694 and $82,831.

That's the whole story of the day. Stocks had a bad one. Bitcoin mostly shrugged.

Now, I'd love to tell you that means something big. It might. It might also just mean that Bitcoin already had its panic on Wednesday and Thursday, when it dipped under $80K for the first time in a month. I don't know yet, and anyone who says they do is selling something.

Why stocks are nervous

Picture a party where everybody has borrowed money to buy the same hot stock. Then the lender walks in and says the rent just went up. That's roughly what's happening with AI companies right now.

Goldman Sachs said Friday that the extra yield investors demand to lend to AI-related companies has widened by 25 basis points, while other companies barely moved (CoinDesk). CoreWeave fell about 12% and is down more than 20% on the week. Micron lost 5.6% and AMD 5.9% (Trading Economics).

On top of that, this week's inflation numbers were hot. Wednesday's CPI came in at 3.7%. Thursday's producer prices rose 1.3% on the month, more than double the forecast. Higher inflation means rates stay high longer, and high rates are bad news for anyone who borrowed a lot.

The date everyone's talking about

You may see this one on your timeline this weekend.

Friday was the 39th anniversary of the Friday before Black Monday. On that Friday in 1987, the S&P 500 fell 5%. The following Monday, October 19, it fell more than 20% (CoinDesk's live blog pointed this out).

Anniversaries aren't forecasts, and I'm not treating this one like a signal. I'm telling you because you'll hear about it, and I'd rather you hear it from me with the context.

Bitcoin's week, in one breath

Monday it opened at $83,678. Tuesday it ran to $84,070 and got turned back, just under the $84.3K ceiling it kept hitting. Wednesday's CPI knocked it down. Thursday's PPI sent it to $79,676, then it bounced $2,900 in two hours. Friday it traded in a tight $80.7K to $82.8K box and closed at $81,500.

Net result: down 2.6% from the weekly open, and the $80K area is still standing. Buyers have now defended it twice (CoinDesk).

The bond market plot twist

You'd think hot inflation would push yields up. It did, for a day. Then stocks sold off, investors ran to safety, and yields fell.

The 10-year ended the week near 5.1%, down about 14 basis points (Trading Economics, CoinDesk). Gold hardly moved at $4,166.

The Fed is a different story. After Wednesday's CPI, traders gave an October rate hike a 45% chance. By Friday it was down to about 12% to 15% (CME FedWatch via FXStreet and CoinDesk). A December hike is still the favorite, at roughly 77% to over 90% depending on the report.

Fed Chair Warsh didn't help clear things up. In Bangkok he said, "I don't prejudge meetings," and added that the AI boom is likely adding to price pressures (CoinDesk).

The oil problem

This one's easy to skip, and I wouldn't.

Brent closed Friday near $110, up more than 5% on the week. Tankers in the Strait of Hormuz are being hit, and flows through it fell to about 11.6 million barrels a day from a normal 17.2 million (Trading Economics). CoinDesk also noted reports of an attack on Saudi Arabia's East-West pipeline.

More expensive oil feeds straight back into inflation. That's why a Friday oil spike matters for a Saturday Bitcoin chart.

The ETF scoreboard

US spot Bitcoin ETFs finished the week $229M in the red (TFTC):

• Monday: −$65.4M

• Tuesday: +$175.6M

• Wednesday: −$261.5M

• Thursday: +$5.1M

• Friday: −$82.4M

That's a second weekly outflow in a row. Last week it was $681M. Ether ETFs lost another $60.2M on Thursday and have had outflows on 12 of the last 13 trading days (SoSoValue via FXStreet).

One bad week isn't a trend. Two in a row is a pattern you keep an eye on.

Not everything went down

While Bitcoin chopped around, a few altcoins had a very good week.

• Celestia (TIA) rose 57% to $0.75, an 11-month high, after the launch of Eden, a new chain for AI agents that uses Celestia (FXStreet).

• Injective (INJ) gained 25% on talk of ETF filings.

• Arbitrum (ARB) rose 7% after Paxos launched its USDG stablecoin there.

CoinMarketCap's altcoin season index rose to 60 from 50 on Friday. That's a reading, not a signal.

Also on the radar

• Strategy bought 250 BTC and now holds 848,250. Strive bought 3,311 BTC and holds 32,773 (FXStreet).

• MSCI finalized rules that could remove Strategy and other crypto treasury firms from its indexes. The list of affected companies comes out November 11 (The Block).

• Circle said USDC settled $36 trillion in the first half of 2026 (FXStreet).

• I found no confirmed hack or exploit dated Friday.

Market dashboard

Open interest is the total value of futures contracts still open. It's up a little, which means some traders are adding positions again.

What I'm watching this weekend

• Sunday 8 p.m. ET is the weekly close (Monday 00:00 UTC). It decides whether BTC finishes the week above or below $81,000.

• Sunday evening is when Asia opens. Last week, Kospi's 8% fall hit before the US woke up.

• Monday is the Black Monday anniversary, so expect the headlines whether or not anything happens.

• Thin liquidity. Weekend moves can be exaggerated because fewer people are trading (FXStreet).

Today's risk rule: Weekend leverage is the same leverage with fewer buyers around. If you're holding some, size it for thin liquidity and write down your exit before Sunday's close.

Today's takeaway

Last week the market had one worry, inflation. This week it had three: inflation, a stock market falling out of love with AI, and $110 oil. Bitcoin sat in the middle of all of it and moved 0.8%.

The line I care about now is $80,694, Friday's low. Under it, the $80K area is next. That's the one worth knowing before Monday.

Inside Premium today

Yesterday's result: our "range" scenario was the one that played out. BTC stayed inside $81K to $83K on the close and the 10-year stayed between 5.05% and 5.15%. The "pressure" scenario needed a close under $81,000 and it never came. We also missed a driver, and I'll show you which.

Today in Premium:

• The weekend plan. What happens if $80,694 breaks, and what happens if $82,831 finally goes?

• 20 BTC key levels, each with its source, including Friday's new high and low.

• ETH after the dip under $2,400: which cited levels sit above and below.

• Options and whale watch: a big put bet on $78,000 and what the options market is saying.

🔒 Scenario C: BTC daily close below $8█,███ with Brent above $11█ → next zone $7█,███–$8█,███

Premium: Scorecard (Friday plan, Oct 16)

Yesterday's plan had three branches. A was "easing" (10-year under 5.05%, an ETF inflow day and a BTC close above $83,000). B was "range" (10-year between 5.05% and 5.15%). C was "pressure" (10-year above 5.15%, ETF outflows and a close under $81,000).

The 10-year ended near 5.09% to 5.12%. BTC closed at $81,500. So B was the live branch.

B · BTC $81,000 to $83,000: right. BTC closed at $81,500 inside that range. It did dip to $80,694 in the 1 p.m. ET hour, $306 under the range, but the close held.

B · ETH $2,400 to $2,500: mostly right. ETH's low was $2,390 and its close was $2,420. It dipped under $2,400 intraday and recovered.

B · gold $4,100 to $4,200: right. Gold closed at $4,166.

A · easing: not triggered. The 10-year didn't fall under 5.05%, ETFs lost $82.4M instead of gaining, and BTC finished well under $83,000.

C · pressure: not triggered. ETFs did lose money, but the 10-year stayed under 5.15% and BTC never closed under $81,000.

Pre-data break, both directions: not triggered. BTC didn't close an hour above $83,000 and didn't break $80,443 before the morning release.

$80,443, the 50-day EMA: held. The low was $80,694 (FXStreet's note lists the EMA).

$83,678 weekly open: still above. BTC closed 2.6% under it.

What we got wrong: the plan's drivers were the 10-year, ETF flows and BTC's close. It left out the biggest story of the day, which was the Nasdaq falling 2%+ and Brent jumping 3.6%. BTC survived that, so the plan didn't fail, but I wouldn't have been ready if it hadn't.

What we learned: a daily plan needs one cross-asset driver, like the Nasdaq or oil, not just rates and ETFs. From today, scenarios include one.

Premium: Key levels (cited)

20 BTC levels, each with its source.

BTC, above:

• $86,996: last week's high (Oct 5, Coinbase daily candle).

• $85,000: a horizontal barrier in FXStreet's technical note (AI-assisted, Oct 16). 21Shares' Matt Mena named it too (The Block, Oct 14).

BTC, below:

• $2,204, $1,971 and $1,827: deeper supports if $2,355 breaks (FXStreet, Oct 15).

Premium: Scenario plan (the weekend)

These are conditional scenarios, not predictions or buy/sell calls.

Where BTC starts: near $81,450, in the middle of Friday's $80,694 to $82,831 range. ETH starts near $2,425.

There's no US data this weekend, so the drivers are different from a weekday.

The drivers:

1. Brent crude. About $110 on Friday, the highest since May. Another jump is a risk-off signal. A drop is relief.

2. The Nasdaq on Monday. After a 2%+ fall, a second down day would test everything.

3. BTC's Sunday 8 p.m. ET close against $80,694 and $82,831.

A · Relief: Brent steadies under $110 and BTC makes an hourly close above $82,831.

• BTC: $83,000 → $83,556–$83,678 (the opens) → $84,062–$84,262 → $85,000.

• ETH: $2,492 → $2,534 → $2,548.

• Gold: toward $4,200 (FXStreet).

• This scenario is wrong if: BTC clears $82,831 but can't hold above $82,000 at Sunday's 8 p.m. close.

B · Chop: Brent flat, thin trading, BTC inside Friday's box.

• BTC: $80,694 to $82,831.

• ETH: $2,390 to $2,492.

• Gold: $4,100 to $4,200.

• This scenario is wrong if: BTC closes a day under $80,694 or above $83,000.

C · Stress: Brent keeps climbing or the Nasdaq extends its fall, and BTC makes an hourly close under $80,694.

• BTC: $80,443 → $80,000 → $79,664–$79,676 → $78,661 → $78,000 → $76,584–$76,824 → $75,000.

• ETH: $2,355 → $2,313 → $2,204.

• Gold: could bid on safe-haven demand, toward $4,200.

• This scenario is wrong if: BTC slips under $80,694 but closes the day back above $81,000.

Combinations: a calm oil market plus a quiet Sunday open is the cleanest case for B. A jump in Brent plus Asia opening lower is C, and C could move quickly because the $80K area has now been tested three times in a week. A rising Nasdaq with a falling Brent is the best case for A.

Pre-Monday break, in both directions:

• If BTC closes an hour above $82,831 before Sunday evening, then a calm Asia open means a run at $83,556 to $84,262. A bad Asia open means sell-the-news risk at the same zone, like Wednesday's spike that faded at $84,000.

• If BTC breaks under $80,694 before Sunday evening, then a worse Asia open means a fast move to $80,000 and $79,664. A steady Asia open means a bounce, but BTC would need to reclaim $81,000 first.

Premium: Options and whale watch

DVOL is about 37.5 (Deribit), a hair under Friday's 37.7. Bitcoin's 30-day implied volatility measure from another provider (BVIV) fell to 38% from a high of 42% (CoinDesk). That's calm. The options market isn't pricing a crash.

The interesting bets. Derive flagged a large bitcoin put spread betting on a drop to $78,000. The $80,000 put was the most traded bitcoin option on Deribit, and the $2,600 ether call was the most traded ether option (CoinDesk, Oct 16). Both fit the picture: some people are hedging the downside and some are still hoping for an upside breakout.

Next big expiry: Friday, October 30, 4 a.m. ET. Crypto Briefing's Oct 8 data had about $11B notional with max pain at $78,000 to $79,000. It's a week old and I haven't refreshed it, so treat it as a rough map. Max pain is a positioning measure, not a forecast.

Derivatives: funding is small and positive (OKX BTC +0.0052%, ETH +0.0019%) and OKX BTC perp open interest is $2.48B. Long ETH futures traders have lost about $500M since Monday (Coinglass via FXStreet), which is part of why ETH looks heavier than BTC.

ETH on exchanges: ETH balances on exchanges rose about 290,000 ETH over three weeks, the highest since September 10 (CryptoQuant via FXStreet). More ETH on exchanges can mean more supply ready to sell. It isn't proof of selling.

Whales: no new confirmed move today. The latest I have is the wallet that held through the March 2020 crash and moved about $378M of BTC on Monday (CoinDesk, Oct 13). Where it went and why isn't confirmed. Moved isn't sold.

What I'm watching

• Sunday's 8 p.m. ET close against $80,694 and $82,831.

• Brent on Sunday evening. A $110+ open would be the first thing to check.

• ETH holding $2,390, Friday's low.

• Monday's ETF flows and the Nasdaq open.

• The next scorecard is Monday's edition, with the weekend close as the first item.
