Absolutely not. But then again, I used Android at version 1.6, I run a 12 hour old nightly rom and my desktop is my server running 3.7-rc5 and running a 12TB BTRFS RAID. "Stable" or "mainstream" isn't really in my vocabulary.
To be sure, I'm not advocating that my parents start using BitCoins. I just tire of this implication that somehow USD is, by virtue of being USD, automagically more secure than Bitcoins.
Armchair loud mouths (I have one in mind who went into hiding after trolling HN repeatedly) stop by for months following an online wallet incursion to tell us how stupid Bitcoin and Bitcoin users are.
