elements. We need to translate all text to Czech while preserving HTML structure.
We need to follow the requirements: maintain meaning, tone, facts, numbers, data accurate, preserve HTML structure, translate naturally, use appropriate Czech terminology for crypto/tech terms, keep proper nouns (names, company names) in original form. Also note: "We need to ensure word count 450-700." That is part of the original instructions for the article creation, but we are just translating. So we don't need to worry about word count, just translate the given content.
The original content has a title: "Bitcoin's 87x Decade Leaves Most Stock Pickers Behind" and slug, subtitle, meta description, keywords. But the user's JSON output only requires "title", "content", and "meta.description". So we need to translate the title, the content (the article body), and the meta description. The subtitle and keywords are not requested in the JSON, but they might be part of the content? Actually, the content includes the article text only. The title and meta description are separate. So we'll translate the title as given: "Bitcoin's 87x Decade Leaves Most Stock Pickers Behind" to Czech. And the meta description is provided: "Bitcoin returned 8,597% over the decade ending June 2026, while only 13% of active large-cap funds beat passive benchmarks. New data shows why index funds keep winning." We need to translate that.
We also need to ensure that the content translation is accurate. Let's examine the content. It has multiple paragraphs and headings. We'll translate each paragraph.
We need to be careful with numbers: keep them as is. Also keep company names: Morningstar, The Wall Street Journal, Dow Jones Market Data, Investment Company Institute, S&P 500, SPY, etc. We'll keep them in original.
Czech translation should be natural. Some terms: "active funds" = "aktivně spravované fondy", "passive funds" = "pasivní fondy", "index funds" = "indexové fondy", "stock pickers" = "výběr akcií" or "akcioví výběrci" but maybe "správci aktiv" or something. We'll decide.
Let's translate step by step.
First, the title: "Bitcoin's 87x Decade Leaves Most Stock Pickers Behind" - we can translate as "Bitcoinovo desetiletí s 87násobným zhodnocením nechává většinu správců akcií pozadu" or something. But "87x" means 87 times. "Decade" = "desetiletí". "Leaves behind" = "nechává pozadu". "Stock pickers" = "výběrčí akcií" but more natural: "akciové výběrčí" or "správci aktiv" but that's broader. Actually, "stock pickers" refers to active managers who pick stocks. We can say "aktivní správci akciových fondů" or "vybírači akcií". But we'll keep it natural.
I'll translate title as: "Bitcoinové desetiletí s 87násobným výnosem nechává většinu vybíračů akcií pozadu" - but "vybíračů akcií" is not common. Better: "Bitcoinové desetiletí s 87násobným zhodnocením nechává většinu správců akcií pozadu" - but "správci akcií" is not exactly. Actually, "stock pickers" might be "investoři, kteří vybírají akcie" but that's long. We can use "akcioví investoři" but that's not the same. Alternatively, we can use "aktivní manažeři fondů" but the title says "stock pickers" specifically. I think "vybírání akcií" is not a noun. Let's use "akciové výběrčí" but that's odd. Perhaps "akcioví odborníci" but no.
Maybe we can say "Bitcoin's 87x decade" as "Bitcoinové desetiletí s 87násobným růstem". "Leaves most stock pickers behind" = "nechává většinu vybíračů akcií za sebou". I'll use "vybírače akcií" but that's not standard. Another option: "správci aktiv" but that's broader. Actually, "stock pickers" is a colloquial term. We can say "aktivní investoři" but that's not precise. I'll go with "vybírači akcií" but it might sound odd. Let's see if there's a standard Czech term: "stock picking" is "výběr akcií". So "stock pickers" = "ti, kdo vybírají akcie" - we can say "vybírači akcií" or "akcioví výbíráči". I'll use "vybírače akcií" (in the sentence). The title: "Bitcoinové desetiletí s 87násobným zhodnocením nechává většinu vybíračů akcií pozadu" - that works.
Now, the meta description: "Bitcoin returned 8,597% over the decade ending June 2026, while only 13% of active large-cap funds beat passive benchmarks. New data shows why index funds keep winning." We need to translate: "Bitcoin za desetiletí končící červnem 2026 přinesl výnos 8 597 %, zatímco pouze 13 % aktivně spravovaných fondů velkých společností překonalo pasivní benchmarky. Nová data ukazují, proč indexové fondy stále vítězí." But we need to keep the numbers: 8,597% - in Czech, we use a space as thousands separator? Actually, in Czech, the decimal comma is used, but percentages are written with a comma? Typically, we write 8 597 % (with a space) or 8,597 %? The original has "8,597%" with a comma as thousands separator (English style). In Czech, we would write "8 597 %" or "8597 %". But to keep accuracy, we can write "8 597 %" (with a space). But the original uses a comma. Since it's a translation, we can keep the number as is? The requirement says "Keep all facts, numbers, and data accurate." So we should keep the exact numeric value, but we can format according to Czech conventions. I'll use "8 597 %" with a space. But the original says "8,597%" - that's a comma as thousands separator. In Czech, the decimal comma is used, but here it's a thousands separator. To avoid confusion, we can write "8597 %" or "8 597 %". I'll use "8 597 %" with a space. Also "June 2026" - we can say "června 2026" but we need to keep the date. "over the decade ending June 2026" = "za desetiletí končící červnem 2026". "active large-cap funds" = "aktivně spravované fondy velkých společností" or "aktivní fondy s velkou tržní kapitalizací". "passive benchmarks" = "pasivní benchmarky" or "pasivní referenční indexy". "index funds" = "indexové fondy". "keep winning" = "stále vítězí".
Now the content: We need to translate the entire article. Let's do it paragraph by paragraph.
Original content:
