. Use appropriate Unicode. Keep proper nouns like "Bitcoin", "Crypto Fear & Greed Index", "S&P 500", "Nasdaq" in English. But note: original uses "Crypto Fear & Greed Index" - keep as is? Since it's a proper name, yes. In Bengali text, we can write it in English script. Also "S&P 500" and "Nasdaq" keep. For "S&P 500", maybe use "এসঅ্যান্ডপি ৫০০" as in text? But careful: original article uses "S&P 500" - we can transliterate? Typically in Bengali media, they write "S&P 500" as is. So keep "S&P 500" in English. Similarly "Nasdaq". Also "Bitcoin" is kept as "বিটকয়েন" in Bengali? Actually the original says "Bitcoin" - should we translate? Requirement says "keep proper nouns (names, company names) in original form". So "Bitcoin" is a name? It's a cryptocurrency name; often it's kept as "Bitcoin" in Bengali text as well, but many Bengali articles write "বিটকয়েন". However, since the requirement says keep proper nouns in original form, I will keep "Bitcoin" as "Bitcoin" in English? But then the title would be "Bitcoin Slides Below $67,000" - I think it's okay to transliterate to Bengali script for proper noun because it's a term. The instruction says "keep proper nouns (names, company names) in original form". "Bitcoin" is not a person or company; it's a cryptocurrency. It's ambiguous. To be safe, I'll use Bengali transliteration for Bitcoin (বিটকয়েন) but keep "Crypto Fear & Greed Index" in English as it's a specific index name. Similarly "S&P 500" and "Nasdaq". Actually "Crypto Fear & Greed Index" is a product name, so keep in English. I'll use English for those.
Check: original meta description says "Bitcoin fell below $67,000, sending the Crypto Fear & Greed Index to a two-month low amid 'max fear'." In translation, I'll keep "Bitcoin" as is? I think it's better to write "বিটকয়েন" because that's how Bengali readers expect. I'll go with Bengali transliteration for Bitcoin
