as in original.
Let's translate:
First paragraph: "The U.S. and Japan intervened in foreign exchange markets together this week for the first time in years, a move that immediately jolted cryptocurrency prices and raised questions about how deep the ripple effects could go."
Danish: "USA og Japan greb ind på valutamarkederne sammen denne uge for første gang i årevis, et skridt der straks rystede kryptovalutapriserne og rejste spørgsmål om, hvor dybe ringvirkningerne kunne blive."
Second: "The joint action, confirmed by the Bank of Japan and the U.S. Treasury on Wednesday, was aimed at halting the yen's slide against the dollar. But the intervention didn't stop at fiat — Bitcoin and Ether both dropped sharply within hours, with traders pointing to a sudden unwind of yen-funded crypto positions."
Danish: "Den fælles aktion, bekræftet af Bank of Japan og det amerikanske finansministerium onsdag, havde til formål at stoppe yen'ens fald mod dollaren. Men interventionen stoppede ikke ved fiat – både Bitcoin og Ether faldt kraftigt inden for få timer, med handlere, der pegede på en pludselig afvikling af yen-finansierede kryptopositioner."
Note: "yen'ens" is correct possessive. "fiat" is used as is.
Heading: "Why the yen move hit crypto" -> "Hvorfor yen-bevægelsen ramte krypto"
Third paragraph: "The connection isn't abstract. Japanese retail investors have been heavy buyers of crypto assets, often using cheap yen loans to lever up. When the yen suddenly strengthens, those positions get squeezed. On top of that, the coordinated signal from two of the world's largest economies spooks anyone holding risk assets — and crypto is still the riskiest bet in the room."
Danish: "Forbindelsen er ikke abstrakt. Japanske detailinvestorer har været store købere af kryptoaktiver, ofte ved at bruge billige yen-lån til at geare op. Når yen pludselig styrkes, bliver disse positioner klemt. Oven i det skræmmer det koordinerede signal fra to af verdens største økonomier alle, der holder risikable aktiver – og krypto er stadig det mest risikable væddemål i rummet."
Fourth: "“The joint intervention highlights global economic interdependence,” the facts note. It's a dry line, but the market reaction wasn't. Within two hours of the announcement, open interest in Bitcoin futures on major exchanges dropped by roughly 8%, according to data tracked by CoinGlass. The yen itself surged nearly 3% against the dollar before settling."
Danish: "“Den fælles intervention fremhæver global økonomisk indbyrdes afhængighed,” bemærker fakta. Det er en tør linje, men markedsreaktionen var det ikke. Inden for to timer efter meddelelsen faldt åben interesse i Bitcoin-futures på større børser med omkring 8%, ifølge data fra CoinGlass. Yen selv steg næsten 3% mod dollaren, før den stabiliserede sig."
Note: "the facts note" - we translate as "bemærker fakta" but maybe "faktaene" but it's a bit odd. We'll keep as "fakta" as in original.
Heading: "What the intervention means for currency strategies" -> "Hvad interventionen betyder for valutastrategier"
Fifth paragraph: "This isn't the first time Japan has stepped in to prop up the yen — Tokyo has done it multiple times over the past year. But having the U.S. join in is new. Washington has historically been reluctant to wade into currency markets, preferring to let the dollar float. That reluctance appears to be softening as global inflation and trade imbalances strain alliances."
Danish: "Dette er ikke første gang, Japan har grebet ind for at støtte yen – Tokyo har gjort det flere gange i løbet af det seneste år. Men at USA deltager er nyt. Washington har historisk været tilbageholdende med at blande sig i valutamarkederne og foretrak at lade dollaren flyde. Den tilbageholdenhed ser ud til at blødgøres, efterhånden som global inflation og handelsubalancer belaster alliancer."
Sixth: "The shift could reshape how traders think about currency hedging. If the U.S. is now willing to intervene alongside allies, the old playbook for betting against the yen might need a rewrite. That uncertainty spills into crypto, where stablecoin pairs and cross-border arbitrage strategies often depend on predictable FX moves."
Danish: "Skiftet kan omforme, hvordan handlere tænker om valutaafdækning. Hvis USA nu er villig til at intervenere sammen med allierede, kan den gamle manual for at satse mod yen have brug for en omskrivning. Den usikkerhed siver ind i krypto, hvor stablecoin-par og grænseoverskridende arbitragestrategier ofte afhænger af forudsigelige valutabevægelser."
Heading: "Crypto market stability in question" -> "Kryptomarkedets stabilitet i spørgsmål" or "Kryptomarkedets stabilitet sættes spørgsmålstegn ved" - we'll do "Kryptomarkedets stabilitet i tvivl" but original is "in question" so "i spørgsmål" is literal. Better: "Kryptomarkedets stabilitet sættes spørgsmålstegn ved" but that's longer. We'll use "Kryptomarkedets stabilitet i tvivl" - but "in question" means uncertain. We'll do "Kryptomarkedets stabilitet i fare" but that's not exact. Let's use "Kryptomarkedets stabilitet sættes spørgsmålstegn ved" - but that's a bit formal. We'll keep as "Kryptomarkedets stabilitet i spørgsmål" - but that's not idiomatic. Actually, we can say "Kryptomarkedets stabilitet er i fare" but that's not the same. Let's think: "Crypto market stability in question" means it's being questioned. So "Kryptomarkedets stabilitet drages i tvivl" or "Kryptomarkedets stabilitet sættes spørgsmålstegn ved". We'll use "Kryptomarkedets stabilitet sættes spørgsmålstegn ved" - but that's a bit long. Alternatively, "Kryptomarkedets stabilitet i tvivl" is acceptable. We'll
