Maybe Mr Craig can give a better answer to this topic, i mean he has fought so hard to be recognize as the real satoshi nakamoto without success, i assume he knows the benefit of being regarded as Satoshi more better

,
in any case, there will be both good and not so good benefit of been satoshi, the good benefit will be the person will go down in history and be known as the man/woman who created a revolutionary technology,
the not so good benefit will be your life will not be the same again, you will loss your privacy = no more anonymous, good and bad people will hunts you down, people will need answers to their zillion questions and the list goes on....
