Why anybody would go to the trouble to buy a Ledger Nanos S to upper their security over their crypto assets, and then download some lousy extension for Chrome, without bothering to verify very carefully with Ledger’s home page whether it is legit or not, beats me.
As always, and as how most people lose their funds in the cryptocurrency space in general, ignorance and carelessness. I swear, even if bitcoin or the whole cryptocurrency space totally collapses and completely dies in the end, the cryptocurrency space definitely taught a lot of people lessons in computer security. Unfortunately though, a good percentage of those people had to learn the hard way.
