I bet that in a few years we will hear about the first scandals involving lost or stolen government bitcoins. Wallet security is not a trivial task for a large organizations, and government agencies have a track record of data security blunders.
One positive effect of this is that government agencies will now be forced to fully understand how bitcoin works, whether they want to or not. That will help campaigners such as the Bitcoin Foundation in their efforts of educating governments.
indeed, there will be theft of government btc.
to edjucate government agency employees is a nice business idea.
