Having run an instawallet- I disagree. Maybe in the future there will be a better option, or better way, but for the moment it's still pretty inconvenient to use crypto and instawallets plug that hole. It's a bad idea to hold a lot of coins anywhere but an off line cold wallet. but then of course, cold wallet coins aren't all the useful for anything.
Dead right on all accounts.
My Android phone got completely hacked the other day for no reason that I can see. It is unknown exactly what capabilities the hacker had, but good security practices make me assume they had full access. So, nix that solution. Unless one is a 'fucking dumbass' that is.
God only knows what kind of spyware permeates most windows machines these to. So using Windows in any capacity also makes one a 'fucking dumbass'.
Like I mentioned earlier, anyone who lets anyone hold any coins in any account as a function of using a service is also a 'fucking dumbass' by the logic of the OP here.
I won't go into detail, but when I did my own cold storage work I paid particular attention to the hardware storage device I used used (and whether it was a cryptographic filesystem or not) as well as the 'wipe' command (or 'shred') in conjunction with any temp files. I also never used any binaries I didn't compile myself. I also chose my secondary crypto system carefully and of course took pains with the physical security of data resulting from my cold storage operations. I cannot honestly say that I took any care against TEMPEST, but I did think about even that.
I won't call anyone a 'fucking dumbass' for failing to employ the rigor I used, but I will say that it is not completely trivial to use Bitcoin with a high degree of safety in spite of the much balyhoo'd assertions to the contrary. I was very rigorous because I expected Bitcoin to be potentially very valuable (though likely a total loss) and it was not worth playing unless on is willing to do it right. I don't fault others for having a different philosophical outlook though, nor for lacking certain technical skill I developed over many years due to my chosen line of work.
