"Investing" in Doge is just as stupid as "investing" $11.8 million into a single Cryptopunk NFT and hoping an even bigger idiot comes along later to buy it from you.

They both have no use or are any good at maintaining value because of inflation. (With Doge the number of tokens, with NFT the sheer amount of possibilities in colour pixels in a matrix and change the size of that matrix whenever you feel like it).
