Okay, the user wants me to write a 900-word SEO article about “how to sell eth in rosario”. Let me start by understanding the keyword. “Ethereum” (ETH) is a cryptocurrency, and Rosario is a city in Argentina. So the article should guide people in Rosario on selling their ETH.

First, I need to structure the article with H2 headings. Maybe start with an introduction explaining why someone would want to sell ETH in Rosario. Then list methods like exchanges, peer-to-peer platforms, ATMs, etc. Each method should have a subheading, steps, pros and cons.
I should include a list of popular exchanges available in Argentina. Binance, LocalBitcoins, maybe some local ones. Also, mention the steps for each method. For example, using Binance: create account, verify, deposit ETH, sell, withdraw.
Peer-to-peer platforms like LocalBitcoins or Paxful could be another method. Explain how to find buyers, set terms, meet safely. Safety tips are important here.
Crypto ATMs in Rosario? I need to check if there are any. If not, maybe mention that they’re rare but possible. Alternatively, suggest checking local directories.
Bank transfers and in-person meetings. Maybe include tips on verifying buyers and secure locations.
FAQ section: common questions like fees, time taken, legal aspects in Argentina. Also, tax implications.
Need to make sure the content is around 900 words. Use bullet points and lists for readability. Include keywords naturally in headings and body. Avoid markdown, just plain text with H2s.
Wait, the user specified to return STRICT JSON with title and content. So the final answer should be a JSON object with title and content. The content will have the article structure with H2s, lists, FAQ.
Check for SEO best practices: keyword in title, H2s, meta description (but user didn’t ask for that). Focus on user intent: people in Rosario looking to sell ETH. Provide actionable steps, local info, safety tips.
Possible challenges: finding specific info about ETH selling in Rosario. Since I can’t browse, rely on general methods applicable to the region. Mention that availability might vary and suggest checking local resources.
Also, include legal considerations. Argentina’s regulations on crypto. Maybe mention that users should comply with local laws.
Make sure the tone is helpful and informative. Avoid jargon but explain terms if necessary. Keep paragraphs short for readability.
