I need to integrate the internal links naturally. For example:
- When discussing profitability, link [Mining Profitability Calculator]
- When talking about configuring hashpower, link [Custom Hashpower Configurator]
- When mentioning sha256, link [sha256 Packages]
- When referencing the marketplace, link [RentHash Marketplace]
- When comparing packages, link [Compare Mining Packages]

The dofollow link to Rent Mining Rigs: I'll mention dedicated rig providers and then link.

Let's start writing. I'll aim for ~950 words. I'll count roughly.

*Self-Correction/Refinement during drafting:*
- Must ensure the JSON is the only output. I'll construct the JSON at the very end.
- The body must be Markdown, but inside JSON string, so newlines need to be preserved or escaped. I'll use proper Markdown with line breaks as part of the JSON string. I'll make sure it's valid JSON.
- I'll avoid any trailing commas.
- The excerpt must be 2 sentences, ~150 characters. I'll craft that carefully.
- meta_title <60 chars. I'll keep it short.
- meta_description <155 chars.

Let's draft the content mentally, then format into JSON.

*Article Body Draft (mental):*
"Riot Platforms recently repaid a $200 million credit facility, releasing previously pledged collateral and signaling a strategic shift in how large-scale miners manage financial leverage. This move underscores the growing importance of balance‑sheet discipline in the sha256 mining sector, where capital efficiency often dictates operational longevity. ... (continue)

I'll structure with headings, lists, table. Ensure links are placed. The table could compare owned hardware vs. RentHash rental across cost, flexibility, maintenance, KYC. 

Let's write the body carefully.

*Word count check:* I'll aim for substantial paragraphs, each ~100-150 words. 800-1,100 is a lot, but doable with 6-8 sections.

*Important:* The internal links must be exactly as specified, with the exact anchor text and URLs. I'll use Markdown link syntax `[text](url)`. For the sha256 one, it has angle brackets in the URL: `<https://renthash.io/algo/sha256>`. In Markdown, I can keep the angle brackets or not, but the spec says `[sha256 Packages](<https://renthash.io/algo/sha256>)`. I'll follow exactly.

The dofollow link to Rent Mining Rigs: I'll add it as `[Rent Mining Rigs](https://rentminingrigs.net)` - this is dofollow by default.

Now, let's construct the JSON. I'll write the body as a multi-line string in JSON. I need to escape newlines or use \n, but typically in these prompts, the model just outputs the JSON with the content as a string, possibly with literal newlines. I'll use proper JSON formatting with the body as a string, possibly using \n for newlines, but it's safer to keep it as a continuous string with \n\n for paragraphs. However, the prompt says "El contenido completo en Markdown" for body. I'll output the Markdown content as a JSON string, likely with escaped newlines or just raw newlines if the system handles it. I'll follow standard JSON practice: use \n for line breaks, and ensure no unescaped quotes.

Actually, looking at similar prompts, the model often outputs the JSON with the body containing the markdown text with actual newlines and formatting, and it's accepted. I'll try to output valid JSON with the body as a string, using \n for line breaks, and escaping any double quotes inside the markdown. But
