Here’s the updated version of your instruction with the character requirement changed:

Post at least one original piece of content on Binance Square using our Article Editor, with a length of more than 300 characters. The post must mention the project account @SignOfficial (https://www.binance.com/en/square/profile/signofficial⁠�), tag token $SIGN, and use the hashtag #SignDigitalSovereignInfra. The content must be strongly related to Sign and $SIGN and must be original, not copied or duplicated. This task is ongoing and refreshes daily until the end of the campaign. Suggested talking point: Sign as the digital sovereign infrastructure for Middle East economic growth.

If you want, I can also create a fully original Binance Square post of 300+ characters based on this for you. Do you want me to do that?
