Unless the celebrity pitches it themselves and there's a unique technology and/or services behind, then maybe yes. If some does make one without a celebrity consent, can possibly get a lawsuit.
Even if a celebrities themselves risk tripping over federal securities laws and, according to legal experts, putting themselves in possible legal jeopardy with the SEC. This is due to untrustworthy management who care solely about the money, and if he ties a coin to a celebrity's name to it, that would rack in the cash. On the Idol Network, celebrities can create their own ICOs and their very own coin, but before they can do that, they would have to have a proposal to be accepted, usually so that fans who buy the coin will actually benefit from it like coin the concerts and having backstage passes and be entitled to exclusive parties etc.
