Since you mentioned it a few months ago, I have started to read into the topic. I bought a new USB drive and installed Tails on it. I am hitting a wall now trying to use it with my Trezor hardware wallet. I followed the steps from the Trezor wiki but I wasn't able to make the TOR browser run the Trezor wallet. I also tried to install the Trezor suite for Linux on it but I also failed with that. It seems there is a lot that I need to learn first, before I can truly make use of Tails. Quite frankly, the documentations and videos I found about it where not really helpful.

Are you using it for CubFinance transactions? Is there a way to use MetaMask with it or do you think that is a security risk? For HIVE?
