I went to the zoo. There are a lot of monkey playing in the metallic nest. And I saw some monkees smiling face. Then I got an idea to make the nft of the smiling monkey. And the I draw this monkey and I also added my own creativity. And draw the etherium cap on the head of the monkey. We know that etherium is the 2nd popular cryptocurrency in the world. This is why I named it as smiling crypto monkey.
