DJ Khaled and Mayweather had an issue about shilling an ICO. And other celebrities hyping or promoting scam coins. Who would actually rely on their words? If you're listening to celebs then you are not ready for this type of market at all.
If you are very much into Cryptocurrency you will not look at those celebrities promoting cryptocurrency but rather you will look at the platform and their roadmap, you will not rely on other people to look on where and what you should invest in, it's a complete disaster if you do that.
