1. What Viking Sats is
Viking Sats is a research brief for high-income W-2 professionals — physicians, pilots, engineers, partners — who have a real job and want a grown-up crypto playbook. It is not a Discord, not a trade desk, and not a personal alert service. We write about Bitcoin and Ethereum and the listed products most readers actually use: spot ETFs, brokerage accounts, IRAs. Same public watchlist for every reader. General research, not advice.
2. What mattered this week
The week after the hike was quieter on the Fed calendar and louder in the brokerage products. Issue 3 closed Sunday morning September 20 near $80,453–$80,454 Bitcoin. Sunday morning September 27, Coinbase and Yahoo both printed near $84,877–$84,883 — about 5.5 percent firmer. The path was a Monday spike, then a grind: Coinbase’s seven-day band since Issue 3 ran from a September 20 low near $80,085 to a September 21 high near $87,397. Ethereum Sunday morning sat about $2,708–$2,709 (Coinbase / Yahoo), roughly 5 percent above Issue 3’s ~$2,579, with a week low near $2,564 (September 20) and a high near $2,807 (September 21).
ETF flows carried the tape more than any new SEP print. U.S. spot Bitcoin funds took in $999.0 million on Monday September 21, then $714.7 million, $346.9 million, $190.7 million, and $134.5 million through Friday September 25 — about $2.39 billion for the five sessions (Farside). Adding Friday September 18 and Thursday September 17 makes a seven-session inflow streak of about $2.98 billion. September month-to-date Bitcoin flows through September 25 are about +$2.70 billion on the Issue 3 Farside MTD plus this week’s sessions. Ether funds were the same direction: +$270.0 million, +$162.2 million, +$104.5 million, +$66.1 million, and +$87.0 million across September 21–25 — about +$690 million for the week (Farside). Combined Bitcoin-plus-ether product flows for those five sessions were about $3.08 billion.
Friday’s listed closes (markets closed for the weekend): IBIT $47.57, FBTC $73.05, ETHA $20.31 (Yahoo) — all firmer than Issue 3’s Friday September 18 prints ($46.02 / $70.66 / $19.92).
Secondary reports of CME FedWatch into the weekend put the next meeting — October 27–28 — nearer a hike than the coin-flip Issue 3 cited after September 16. One commonly cited flash around September 26 put another +25 basis points near ~64% (hold the rest). Those odds will still move with the data. Process on the same calendar: no new CLARITY cloture this week. The September 15 result still stands — 49–50, short of sixty, with a motion to reconsider on the table. We report the process, not a price thesis.
3. The useful frame this week: location, not the streak
Issue 3’s frame was size for October 28, not Wednesday’s dump or Friday’s rebound. That date has not moved. This week’s free frame is the constraint that survives even when flows are green: account location.
A $2.4 billion Bitcoin-ETF week and a quiet Fed week can both be true. Neither answers whether the next IBIT or ETHA share belongs in a taxable brokerage account or a tax-advantaged IRA — or whether the reader wanted the coin itself instead of the fund. Thesis is “do I want Bitcoin or Ethereum exposure.” Location is “which wrapper holds the exposure.” Those are different questions. Mixing them is how a W-2 reader turns a research brief into an accidental tax event.
A few public mechanics, not a recommendation:
In a taxable brokerage account, spot Bitcoin and Ethereum ETF shares are securities. Sales typically show up on year-end brokerage statements (Form 1099-B and related). Wash-sale rules that apply to stocks and ETFs can disallow a loss if the same or a “substantially identical” security is bought in the 30 days before or after a loss sale (IRS Publication 550; standard brokerage education pages). Direct coins sit under the IRS digital-asset rules as capital assets — a different reporting path from listed ETF shares. In an IRA, gains and losses generally do not hit the current-year return the way a taxable sale does; Traditional and Roth distribution rules differ. Selling at a loss in a taxable account and buying the same security inside an IRA can still create a wash-sale problem under published IRS guidance — educational fact, not a playbook.
A practical rule, not a recommendation: treat location as a decision you make once with eyes open, not as a patch after a green ETF week. If the position only made sense while Monday’s $999 million print felt like confirmation, it was sized for a streak. Streaks reverse. Account wrappers do not. Paid depth from October 4 is sizing, taxable vs IRA, and ETF vs coin — not more coins or hot takes. This free letter only names the constraint.
4. Public watchlist (facts, not recommendations)
Same list for every reader. Sunday morning September 27 prints — not a buy list, not an alert.
Bitcoin (BTC-USD): ~$84,877–$84,883 Sunday morning Sep 27 (~8:00 AM ET; Coinbase product/bid-ask and Yahoo). ~7-day Coinbase high ~$87,397 (Sep 21) / low ~$80,085 (Sep 20). Issue 3 Sunday AM Sep 20 ~$80,453–$80,454.
iShares Bitcoin Trust (IBIT): $47.57 close Fri Sep 25 (Yahoo); 0.25% expense ratio. (U.S. equity markets closed for the weekend.)
Fidelity Wise Origin Bitcoin (FBTC): $73.05 close Fri Sep 25 (Yahoo); 0.25%.
Ethereum (ETH-USD): ~$2,708–$2,709 Sunday morning Sep 27 (Coinbase / Yahoo). Issue 3 Sunday AM ~$2,579. ~7-day Coinbase high ~$2,807 (Sep 21) / low ~$2,564 (Sep 20).

U.S. spot Bitcoin ETFs (Farside): Sep 21 +$999.0M; Sep 22 +$714.7M; Sep 23 +$346.9M; Sep 24 +$190.7M; Sep 25 +$134.5M; week ≈ +$2,386M; seven-session streak Sep 17–25 ≈ +$2,978M; Sep MTD through Sep 25 ≈ +$2,699M. Ether funds (Farside): Sep 21 +$270.0M; Sep 22 +$162.2M; Sep 23 +$104.5M; Sep 24 +$66.1M; Sep 25 +$87.0M; week ≈ +$690M.
5. What we will cover next
This is the last free Sunday. Paid depth starts October 4 at $20/month or $200/year: sizing, taxable vs IRA, ETF vs coin — not more coins or hot takes. The free layer stays what it has been: the week’s facts, one constraint, and the public watchlist. The next FOMC is October 27–28; we will treat October 28 as the decision date the same way we treated September 17.
If you have a real job, you do not need a new thesis every Sunday. You need the week’s facts, one constraint that survives a quiet Fed week, and a date for the next actual decision. That is the brief.
