400-600 words. We'll write around 470 words. Include HTML structure. We need to embed the opening tag

. We'll put the headline inside that? Actually they want the headings inside the article. Might want to put the article heading inside

tags. But they said HTML:

. This is confusing. Perhaps they want the article to begin with that exact snippet, then the lede continues. So we can start with:

Kraken erweitert europaweite Krypto-Infra mit Karte und Kredit

That includes the headline inside h2 tags inside a paragraph. Then we can continue with lede paragraph after that? They said lede paragraph ->

Hintergruende

... So maybe the lede is separate after the opening snippet? Actually "Lede paragraph ->

Hintergruende

->

Reaktionen aus dem In- und Ausland

->

Ausblick

". So maybe the lede is just a paragraph (no heading). So we can start with

... lede ...

then the headings. But they also said HTML:

. So the first tag is that combination. Perhaps they want the first heading (the article title) to be inside that combination. Let's just put the first heading as that snippet, then after that we can have lede paragraph, then

Hintergruende

, etc. To be safe, we can structure like:

Kraken erweitert europaweite Krypto-Infra mit Karte und Kredit

Die Krypto-Börse Kraken hat ... (lede)

Hintergruende

...

Reaktionen aus dem In- und Ausland

...

Ausblick

...

Gates Of Memes ist ein Satire-Medium...

That satisfies structure: lede paragraph present, then headings. Now need to ensure we include fictional sources like "Ein Mitarbeiter des Finanzministeriums, der anonym bleiben wollte, erklärte..." etc. Word count must be 400-600 words. Let's approximate. We'll write about 470 words. Now
