Is Bubble a real website?

Could you please clarify for me if "Bubble" is indeed a legitimate and operational website? I've heard some discussions about it but I'm not entirely sure if it's a reliable source or just another hoax. Could you provide some insights into its authenticity and functionality? Also, is it safe to use for personal or business purposes? Your expertise in the field of cryptocurrency and finance would be greatly appreciated in answering these questions. Thank you for your time and assistance.
