Transferred from a friend, the inspiration this editing brings to product managers:

"If I were a product manager at an exchange, I would have already implemented a feature that adds a hidden watermark to the profit and loss sharing chart, allowing images to be submitted to the official website for verification of authenticity and whether they have been tampered with.

The so-called crypto industry doesn't even have such encryption and decryption verification functions, while platforms like Douyin and Douban, as well as many internet companies' internal forums, know to add hidden watermarks to screenshots to track the publisher."
