So.. if I found the right website, Akon is creating his own coin, Akoin. From their website[1]: "AKOIN IS THE EXCLUSIVE CURRENCY OF THE AKOIN ECOSYSTEM". Great, another unnecessary coin. I'm not saying that Akon is a bad person, but if he really wanted to help, pretty much every use-case indicated on their website can already be done using BTC and ETH. I'm guessing that some people just proposed this idea to Akon and asked for permission to use his name. Pretty much the same with Manny Pacquiao's PAC token.

https://www.akoin.io/Agreed, already there were more coins based on personalities. Some even created by them as they're good at programming. There needs to be some use case that is unique to get good value to the project and the coin. Here the coin might get popularity as it is named based on his name, but when it comes to use case and growth it won't attract good investors choose it.
