It's hard not to like gmaxwell's interview who was interested in alternative payment systems even before Bitcoin. He added to the technical development of the network. I laughed when I read the part were the police thought he was growing pot due to the electricity consumption.
In question 7. 3, gmaxwell talks about the lack of a feature to ban specific users from certain sub forums. I thought that already existed. Didn't gmaxwell ban a user from posting in Development & Technical Discussion some time ago for constantly writing wrong suggestions? Maybe I am going crazy.
With all that in mind, my vote goes to
Some users suggested qwk and CryptopreneurBrainboss as the best interviews so I took a look at those as well.
I like how qwk had a very good understanding of what bitcoin would one day become in his student days. But he is still human and made some mistakes that ended up losing him money on MtGox.
CryptopreneurBrainboss went from an airdrop participant to a legendary member with 1500 earned merits and a campaign manager. There are sooo many good interviews, unfortunately, I can only pick one.
