It is definitely a good choice to accept money in bitcoin, you will get paid and you don't have to invest in any other place like stock market and all were you have to rush every now and then and get saved from aggressive buyers and sellers,
just accept the money and see it growing.
A really smart move for lawyers that have known bitcoin for long. They could insist first that they accept btc but I still doubt that their clients will do that. Their clients must be hoarding a lot of bitcoins so I guess only a few lawyer could have that payment opportunity.
This is true which instead for those people who wanted a service from a lawyer they would surely tend to make use on their own local fiat currency rather than on their bitcoin itself since they do know the possibilities on making profits by just hoarding bitcoin for a long period of time. Instead on wasting it up they would rather save it and use fiat instead but well people do have different decisions when it comes on spending their bitcoins.
