I received a PM from someone at a Portuguese newspaper who I think meant to post it publicly, so I'll respond publicly here.

You have contacted Satoshi Nakamoto. Does it seem to you only one person or a group of developers?

I think Satoshi is probably one person.

Does bitcoin seem cyberpunk project to you? In that case, can one expect they ever disclose identity?

Not sure what the first part of the question means. I don't expect Satoshi to voluntarily reveal his identity in the near future, but maybe he will do so eventually?

In that case, the libertarian motivation wouldn't be a risk to anyone who invest in the community? Like one this gets all formal and legal, it blow?

Don't understand this one either.

Is it important to know right now its origins? The author from the blog LikeinMirrorr, who says the most probable name is Nick Szabo, argues there is a concern on risk: if Szabo/ciberpunk is the source no risk, but it maybe this bubble - pump-and-dump scheme to enrich its original miners - or a project from federal goverment to track underground transactions. What is your view on this?

I'm pretty sure it's not a pump-and-dump scheme, or a government project.

Do you also think Szabo is the most probable name?

No I don't think it's Szabo or anyone else whose name is known to me. I explained why I don't think it's Szabo to a reporter from London's Sunday Times who wrote about it in the March 2 issue. I'll try to find and quote the relevant section.

How long have you start working on your ideas of criptocurrency? Have you used other pseudonyms online? Are you Szabo?

I worked on it from roughly 1995 to 1998. I've used pseudonyms only on rare (probably less than 10) occasions. I'm not Szabo but coincidentally we attended the same university and had the same major and graduated within a couple years of each other. Theoretically we could have seen each other on campus but I don't think we ever spoke in real life.

In your opinion, why has bitcoin succeed?

To be honest I didn't initially expect Bitcoin to make as much impact as it has, and I'm still at a bit of a loss to explain why it has succeeded to the extent that it has. In my experience lots of promising ideas especially in the field of cryptography never get anywhere in practice. But anyway, it's probably a combination of many things. Satoshi's knowledge and skill. His choice of an essentially fixed monetary base which ensures early adopters large windfalls if Bitcoin were to become popular, and which appeals to people who distrust flexible government monetary policies. Timing of the introduction to coincide with the economic crisis. Earlier discussions of related ideas which allowed his ideas to be more readily accepted. The availability of hardware and software infrastructure for him to build upon. Probably other factors that I'm neglecting.

(Actually I'd be interested to know if anyone else has written a better explanation of Bitcoin's success. Can anyone reading this comment point me to such an explanation?)

Finaly, what do you see as future? Wall Street has announced they wil start accepting applications for bitcoin and other digital currency exchanges. How do you see this milestone?

Don't have much to say on these. Others have probably thought much more about these questions over the past months and years and are more qualified than I am to answer.
