For clarity, questions & answers are reported here

Would you ever consider doing a giveaway of some of your products?

Would you consider having your products support other emerging cryptocurrencies in the future, especially Bitshares and Ethereum?

Have is you relation with the Mycelium Wallet team, I know there is support between the Ledger Wallet and Mycelium, how do you collaborate about such stuff?

Do you consider taking venture capital? Or maybe you already have?

Given French reputation about being quite anti business friendly, extremely beaucratic etc. have you ever considered moving abroad to for instance the UK, or US/Silicon Valley?

How do you think hardware wallets will evolve in the future? What kind of products do you expect to sell in 5 years?

I want to hold a considerable amount of bitcoins, and I'm looking for a very resilient and attack-proof solution. The problem with the current solutions in the Bitcoin space is that [...]

Can you tell me more about the bitcoin scene in France? How many people do you think have a bitcoin wallet?

What do you think about the Bitcoin VAT ruling and the recent EU controls proposal

Have you thought about collaborating with NFC payment Bitcoin startups such as Onepay and Plutus , or even entering that space yourself?

Can you provide a link to how secure elements work. I'm yet to find a good (simple, yet informative) guide.

Do you mind to tell us which percentage of your net worth and/or liquid assets you hold in Bitcoins ?

This one just for you can you tell us about the state of Bitcoin in France (VCs, government, banks, entrepreneurs) ?

What gets you excited in your future product line. Also what worries you the most about Bitcoin's sustainability?

For users comfortable with btc what is the benefit of a "usb" disk like hardware wallet. I have read your site and reviews but this makes little sense to me. How does your product improve on an encrypted usb thumb drive, I mean, that's what you're selling right?

Why does La Maison du Bitcoin in Paris require showing personal ID for using the Lamassu ATM? Is this a government requirement or some kind of pre-emptive compliance?

We have done that from time to time, for instance like this giveaway on Reddit a few month ago. We do not have immediate plans for a giveaway; but we'll participate to Bitcoin Black Friday on November 27th.As we are building secure signature devices, our low level APIs are in theory compatible with any kind of altcoin of blockchain. We just need to make sure that the curves are supported or that they follow already existing standards. However, a client application (the software wallet) is needed to communicate with the chip, and this is usually the biggest challenge.If one day another cryptocurrency or dapp would have an important usage market, we'd for sure consider developping solutions for it.Mycelium is open source and has always shown interest for new features. This is why we have almost always worked on showcasing our new products on this wallet. Usually, we implement the changes and features on our side, and request a merge. We then coordinate all PR stuff to announce the news.We are already VC funded, with a seed round in February 2015. We are most probably planning a Serie A (a new venture round) in 6 to 18 months in order to accelerate our growth.We have already opened an office in San Francisco (through a 100% owned subsidiairy), but this decision was mainly related to business development (as most of the Bitcoin related projects are in the Silicon Valley). Being in France has actually a lot of advantages: the stance of the government on startup has evolved and we have access to a lot of grants and public funds which is helping us a lot. Also, France being the land of the smartcards, hardware and security engineers are much more qualified here than in the USA (with respect of our very specific engineering scope).If we require hardware wallets, it's because generale purpose computers and smartphones are currenctly insecure. With the development of Trusted Execution Environment (TEE) technology, we may not need dedicated secure devices anymore in a few years. The TEE is basically a virtualization of a secure element running in isolation from the main OS, and is right now available in high end Samsung phone (such as the S6). For more information, you can refer to the Ledger Trustlet Regarding new usages, independently of the product form factor, we are evolving from pure hardware wallet (like the Ledger Nano) to personal security/privacy devices (like the Ledger Blue). These products will not only secure your digital assets, but also manage your digital identities (FIDO) and help build secure communications (for instance having encrypted Slack channels, managed in real time by the Blue, so you can protect your trade secret whilst benefiting the coolness of Slack).Having a single address based device with no communication except a camera is not something that we intend to develop, because we do not believe it will add any security compared to our existing solutions. It may not be suited to what you are looking, but in term of security it matches your requirement.USB/NFC/BLE communications can be deactived from the settings, and parsing a QRcode is also subject to attack (you can add an overflow and arbitrary blob on a QRcode). So ultimately it comes back to good security practice and clean code. Using a Chrome app is not an issue; it's just an UI. It's not made to be trusted. You need to always verify the signature on a trusted display (second factor).Finally, I wouldn't recommend to use a hardware wallet (whatever it is) to hold a considerable amount of bitcoins. If you had one ton of gold, would you keep it home? Even if you had the best safe of the world, you would still have the risk of someone coming home and putting a gun on your children. My recommendation would be to use multisignature with different hardware wallets At La Maison du Bitcoin, we are operating an exchange counter where people buy and sell bitcoins against euros (cash or payment cards). The VAT question is something we have solved a few months ago by sending a letter to the fiscal authorities (they have to answer). The EU VAT ruling was then not a surprise, and we of course rejoice that it has been made official at the European level.Michel Sapin (Minister of Finance) announced today the financial counter terrorism measures which will be taken in the coming weeks. None are related to cryptocurrencies (which are not at all mentionned), the takedown is targetted on anonymous VISA and Mastercard payment cards, as well as cash.The Bitcoin scene is not extremely active in France; we have a lot of engineers and enthousiasts, but the usage in shops (both online and physical) is quite poor. We have everyday a few dozen of people entering our Bitcoin space, buying bitcoins or asking for informations. Most of them are using the currency to play online (poker, betting, ...) and a few to invest/HODL.Yes, we could easily offer an external device that would help on implementing those features where they can't be (typically on an iPhone with Ledger Blue). We have no plan to enter that space directly for the time being.It's hard to find some good references, so I'd suggest to have a look at different hacker conference presentations. For example that one describes the specific hardware security features you'll find in a typical secure element.I hold in bitcoins about 5% of my net worth and about 25% of my liquid assets.State of Bitcoin in France is clearly not at its best. There have been only two VC investment related to Bitcoin in France (us and Paymium), banks refuse to open accounts for Bitcoin related businesses (we have been kicked out of two banks already), regulator has a strong negative stance over cryptocurrency (but it's far from being banned or anything, the law is quite positive in the sense that Bitcoin is not regulated at all) and entrepreneurs are not legion. The number of French Bitcoin related startups is quite low, and didn't evolve much in the last year.It is like it is, and we certainly don't complain. As I stated in another answer France is quite a nice place for startups and one can always move its bizdev operations in the Silicon Valley.Hardware wallets are going to evolve to personal security devices. Not only they'll be used to secure your bitcoins or other digital assets, but they'll manage your digital identities (FIDO) and secure your communications. The Ledger Blue is the first step in this direction, and we are very excited to see what the developer community is going to do with it.Regarding Bitcoin's sustainability, this is a tough question. There are so much parameters at play that I quite see it like a chaotic system where equilibriums are scarce. In any case, Bitcoin is going through difficult times: the adoption is poor, startups are pivoting, and communities are pitchforking each other. As many VCs have told me, winter has come. But I'm still very confident about the resilience of Bitcoin; we thought it would take a few month to scale, but most probably we'll need a decade. It's a game of patience.The Ledger Nano is not a USB drive but a secure computer on a microchip. It will safeguard your Bitcoin private keys and sign transaction within the secure element. Thus, secrets are never revealed to the host computer (contrary to a USB thumb drive which would indeed offer absolutely no benefit).To mitigate malwares and man in the middle attacks, the Nano has a second factor verification of the transactions using a physical security card or a smartphone securely paired to it.As Bitcoin is not an official currency, we are not required by law to do any KYC/AML. This is therefore a pre-emptive compliance, following our own set of processes and amount limits. It's a personal choice, guided by the wish to build a long lasting business.
