So, I'm wondering if my system of protecting my bitcoin is totally secure.
If I have an old laptop, and I boot into tails linux from a flash drive, and download electrum on there, and only ever connect to the internet at my home WiFi, and only ever visit Coinbase (GDAX) and Gmail, are their opportunities to steal my bitcoin?
Is there hardware risk? Would I need to wipe the drive completely, or can I purchase a hardware wallet that transacts without connecting to a laptop?
Is there WiFi risk, or are Electrum, Coinbase, and Gmail all encrypted connections so it wouldn't even matter if there were a man in the middle? (am I confusing things here?)
Is there risk with Electrum? Should I download the core Bitcoin client instead?
Obviously no cameras or microphones in the room when you use the dedicated laptop, right?
