I'm hearing WhatsApp coin for the first time in this thread, if it's real, then it's probably not listed yet. Although I think that developers can capitalize on important names for their coins to gain popularity, this does not mean that the coin has any affiliation with original owner of the name. Yesterday I heard of Satoshi coin, which I doubt the original Satoshi, has anything to do with the coin, my signature campaign, Eloncoin, which I'm yet to know if Elon Musk, is the owner, are examples of giving VIP names to new coins to gain massive popularity.
Make your choice of investment from crypto coins that are listed, not from the ones from hearsays, so you don't fall victim into the hands of scanners.
