Not sure I'd call it money laundering, it's all being done in the clear.

But it's certainly a scam:

The paper released Thursday shows that Trump and his family assume no liability. It indicates that none of them are directors, employees, managers or operators of WLF or its affiliates, and said the project and the tokens “are not political and have no affiliation with any political campaign.”

There's a strong implication that launching this during his campaign means it's tied to the campaign, but it's really not.
