I believed it too initially, but then came across some Tweets and found out it's a stunt.
I have to admit I did not know who is in the picture, but that photo is published on almost every article which is related to DB in last few days. Same as title of this thread, this was just one extra joke in the alleged connection of the bitcoin with DB case.
However this was a very good PR for Fielding & Nicholson, and we know that there is someone who make good suits which can be paid with bitcoins.
Don't worry me too I failed in As for Fielding & Nicholson they didn't even use Bitcoin I think, not sure where the BTC bag comes from. I have seen people asking them where to buy it. And right after this news, they started to accept BTC.
Nice free advertising if you ask me.
Also, did you notice the 'S'. I wondered why Bitcoin is mentioned in plural
