These are the last remaining BUX. Only 181 from over 70 million were saved. Sent back in time from the year 2140 to be stored as NFTs. Most BUX show signs of deterioration many with pixels missing along with discolouration.

A short message mentioned they were damaged from an unforseen phenomenon called the Fade. The Fade swept through the metaverse destroying everything pixel by pixel.

It's unknown exactly why only BUX have been sent back in time. Best to keep them safe as only time will tell.
