We can't really be too certain something wrong won't happen with this. I've read something here where a user got hacked while trying to update their wallet and all the funds moved out. I don't know how that happened but it was a shock anyway.

Doing this regularly will easily expose your wallet. Someone can stumble on where the littered vitals are hidden and the funds are gone just like that. Limit doing this. I make a copy of mine only once. I don't even keep it like something I'm hiding. I keep it where I keep other regular stuff so that even if anyone stumbles of it, they won't know it's something important. I'm practicing that principle of the best way to hide something is to expose it or put it in the open.

This should've come as number one warning to heed to on the list.

This is apt! For those who think they want to save cost by using public WiFi to assess anything confidential, they aren't doing themselves any good. Wifi in the public space should be for less serious browsing or Netflix and all of that, not something that involves high level of privacy.
