Three meme coins that could see a downturn in May:

1. $ApeCoin (APE-USD): Initially buoyed by its association with the Bored Ape Yacht Club (BAYC) NFT project, ApeCoin's popularity has waned due to internal issues and a declining focus on NFTs.

2. $Shiba Inu (SHIB-USD): While riding the hype of the 2021 crypto boom, Shiba Inu's lack of practical use beyond speculation could lead to dwindling investor interest as the market corrects.

3. $Bonk (BONK-USD): Leveraging the negative sentiment in the market, Bonk gained attention but lacks innovation and faces tough competition in the meme coin space, potentially resulting in a significant price decrease amidst bearish sentiment.
