Some concerns, looking forward to your answers:

1. Currently you have only 3 members in the project? 2 developers and 1 finance/marketing? Not enough at all to create a hardware wallet,
for comparison - Trezor wallet's page lists 21 team member, and you aim to create a wallet 'far better than Ledger Nano S and Trezor'

Seems you plan to expand the team, what is the planned staff? And according to roadmap, in Q3 you will be 1. expanding 2. building and updating web and mobile wallets - all simultaneously,
and in Q4 you already have a hardware wallet. Not very realistic.

2. Your whitepaper states that you already 'added unprecedented levels of protection' into your HW. Do you have a security expert in your core team? Why he/she is not listed?

3. If you are building a hardware wallet, why your webpage is only about masternides? Lol... The only mention is in a roadmap.

4. Wifi and sim card support won't make your device more secure, on the contrary it makes it more exposed. You stated it yourself: "The best way to keep your key safe is to limit its exposure to the internet",
but you provides possibility of constant internet connection.
The whole point of hardware wallets' security is that they are offline, and that is why Ledger and Trezor are most secure currently - the only moment when the go online is when they are connected to PC which is connected to internet.

5. the more device is sophisticated, the more it's vulnerable, and you aim to add a whole bunch of complex stuff - wifi, sim card, QR, GPS support and 400 different currencies which require support of huge amounts of different protocols and standards. How do you plan having 'the most advanced level of security' mixing this altogether?

6. Your whitepaper is 3 pages without team members and only mention of your company is that it's founded in United Kingdom.
Considering your high aims your whitepaper looks very lame, not even roadmap is added there. Also, seems you are not hiding your faces, why then hiding your company profile?

If you are serious team with serious intentions, then would like to know more info about team members and company, skills and previous experience.

7. And the last - what is the role of your coin? how is it connected to building a hardware wallet? and for what reason do you require masternodes?
