You need to find an exchange that will exchange max for bitcoin.
You then sell bitcoin for money at an exchange that does it
Thanks for your reply - that's what I suspected - there still isn't an established exchange system for cryptocurrencies.
BTW, don't confuse fiat currencies and money - they are not the same thing. Whereas fiat currencies can be used as media of exchange they are not reliable wealth storage vehicles and hence do not qualify as 'money'.
