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.
Not to generalize celebrities but most of them only have the means of investing while lacking the proper understanding and fundamentals of the topic. To give you an example, Mayweather is absolutely considered one of the greatest boxers of this time but his lacking of basic investment methods hinder him from making proper decisions. In addition, they get easily attracted and captivated by ICOs while failing to do background checks or research on the company.
If I were to base my decision on someone, I would rather listen to an financial/trading expert who has a background on investing compared to celebrities who know little to nothing about investment.
Celebrities will advertise anything. After all, they get a fee for this and, moreover, not a bad amount. So why not earn a little, and even remind yourself through advertising. After all, they get paid for advertising immediately and with money, and not tokens like bounty hunters
That is their job in the first place since they target the audience with little understanding of investment. Unfortunately, that is the sad state of some advertisements. Lack of authority in promoting something that does not coincide with their profession line or background.
