Solana Advertisement Removed After 10 Minutes in Shanghai, Critics Point to CZ

WHY IT MATTERS

This story touches on two important topics for anyone learning about crypto. First, China has banned most cryptocurrency activities, meaning advertising crypto projects there is very unusual and likely to attract regulatory attention — similar to trying to advertise something that is not permitted in a particular country. Second, the crypto industry has major competing ecosystems (like Solana and Binance's BNB Chain), and rivalries between them can lead to unverified accusations. For newcomers, this is a reminder that claims made on social media about who caused what should be treated with skepticism unless backed by evidence.
