It does not matter, anonymous person can scam you, person with published name, LinkedIn etc. can too. Company running a coin can go bankrupt. In each of those occasions, you lose money. How are you going to get your money back from person who does not have any money left? Putting him in prison won't return you the money How are you going to get money from company which went bankrupt and has no money?

Ask yourself - if you founded a coin which has tens or hundreds M USD marketcap and possibly have access to let's say 10% of total supply (for operations, marketing, devs etc.), would you be comfortable walking on street knowing that people know you have millions or tens of millions of USD wealth? There are legit reasons behind some cryptofounders going anonymous and I respect that.
