In writing, the letters "O" and the number "0" can easily be confused, a common occurrence in the domain field. In a recent embarrassing incident, an experienced domain investor nearly purchased "0KR.com," mistakenly thinking it was "OKR.com," almost confirming the payment.
The incident began with a user who owned "0kr.com" posting on Twitter, claiming that the domain was priced at $7,777. Drew Rosener, an experienced domain investor, had previously been pursuing the three-letter (LLL) .com domain OKR.com. Believing it to be the domain he was after, he replied to the post, saying, "I will take it, can pay right away."

Fortunately, this misunderstanding occurred on Twitter and not on platforms like Sedo, where triggering the "buy now" button is instantaneous. Drew quickly realized his mistake and retracted his offer.
Due to differences in fonts, the number 0 can closely resemble the capital letter O. Therefore, extra caution is needed in such situations, especially under the influence of certain beverages.
Speaking of the three-letter domain "OKR.com," it's worth mentioning its owner, the Chinese internet giant "ByteDance." Upon checking the webpage, it was discovered that the domain belongs to ByteDance's subsidiary, "Beijing Feishu Technology Co., Ltd." The domain OKR.com was registered in September 1998, making it a highly valuable three-letter .com domain.

As for the exact number of domains ByteDance owns, there is no precise figure, with a focus on pinyin domains. ByteDance has always been a mysterious and intriguing presence, with their domains seemingly constantly emerging. Examples include the AI model's bean bag "doubao.com" appearing in June and the recently filed "zijietiaodong.com." Well-known brands like "Douyin, Toutiao, Xigua," etc., are also widely recognized on the internet.
