1) MESSAGE FOR CURRENT Bitfi USERS: There are still thousands of people who are using the original Bitfi device. It is a remarkable wallet with a very unique security mechanism. Bitfi provides complete protection from seizure, theft, loss of device, or confiscation. There is no 
2) possibility of gaining access to your coins in this scenario, which is the most common way for extraction of funds. This can’t be done with your #Bitfi due to a simple & elegant approach of not having any user data (such as private keys) on device, making any attempts to
3) perform an extraction futile. However, as with almost any new technology the first version is almost never perfect and issues are discovered as the device goes out in the field for use by the public. The weakness with the first Bitfi is that it (like any other hardware wallet)
4) can be modified or altered either via some clever modification that an attacker can perform to circuit board or via code injection using the device’s data port. An attack like this might look as follows: you leave the device on your desk and go on vacation. An attacker
5) breaks in & modifies the device and leaves it in the same place where you left it & its done without scratches or any other physical signs of tampering. Then the attacker patiently waits for you to return and use the device again, user having no idea that it has been altered.
6) Depending on what was done, the attacker may then be able to capture whatever you are typing remotely or may obtain this data by having to gain physical access to the device again when you are not there. Every hardware wallet is susceptible to this type of attack (except
7) one, but more on that in a moment). To date, we are very pleased to say that after 3 years with thousands of active users (some of whom are securing their entire life savings with Bitfi) that not a single user has ever lost funds due to any hack or exploit. And it is our core
8) mission to keep it this way indefinitely. As a result we are concerned that there are thousands of units of the original Bitfi in the field and that at some point it is almost inevitable that someone might be exposed to this type of attack. The Bitfi.2 replaced the original
9) Bitfi and it is the result of painstaking effort and attention to detail with further assistance from some of the most experienced security professionals. There is no practical way for someone to tamper with or modify the Bitfi.2 and so if you are away from it you never need
10) to worry about using the device again. Perhaps someone could develop some very exotic attack, but they likely would need the device in their possession for at least a month and it would be extremely costly and likely a project that would only be pursued by law enforcement
11) for a high profile target, where it’s a matter of national security. Even then, for the attack to work the device would have to be returned to the user in a manner that they do not notice that it had been missing for that time and don’t notice that it’s modified. We believe
12) that the Bitfi.2 is the most secure wallet system that currently exists and by a wide margin. We really encourage all existing users who are using the first Bitfi to switch to the Bitfi.2 for complete protection in any scenario (short of things like someone placing a camera
13) where you use your Bitfi.2 to record your key strokes, but this is something that is beyond the scope of what can be done by a device manufacturer, the user still must exercise basic common sense and diligence). To encourage users who are still using the original Bitfi to
14) switch to Bitfi.2 we will supply these device at cost so even if you feel that you are not at risk of someone gaining access to and modifying your device, it still makes sense to switch. If you own the Bitfi, please go ahead & purchase the Bitfi.2 using the coupon code
15) CAECD6 at check out. This will automatically apply a $150 discount to your purchase. Please note that this coupon code can only be used by existing Bitfi owners. Your purchase will be rejected if we can not verify that you are an existing Bitfi user. Please upgrade. This is a
16) small price to pay to get that final milestone in security so that we can all be sure that no one using this wallet technology will ever experience a loss, regardless of how unlikely it is to happen.
