Is ATOM still usable?

Could you please enlighten me on the current status of ATOM? I'm a bit out of the loop and I'm wondering if it's still viable for transactions or investments. Has there been any recent developments or changes that might affect its usability? I've heard some rumors about cryptocurrency markets being volatile, so I'm cautious about making any decisions without proper information. Would you mind sharing your insights on this matter? Your expertise in the field of cryptocurrency and finance would be greatly appreciated.
