Why is atom shutting down?

I've been hearing rumors that the Atom project is shutting down. Could you please elaborate on the reasons behind this? I'm quite interested in understanding the circumstances that have led to this decision. Has there been a significant decline in user base or trading volume? Are there any technical challenges or security issues that have made it necessary to shut down? Additionally, what impact will this shutdown have on the cryptocurrency market and its investors? I'm keen to know your insights and analysis on this matter.
