Never.   For those at the top, life is life a game of Monopoly where they are trying to control as much as possible.  War is very profitable for a lot of companies as well...

The elimination of organized religion would have a better shot at eliminating war than BTC.

Could just hide the app, no?  How much time do they take searching phones?

Airbitz is good because you can uninstall the app completely, travel, then reinstall.  When you "log in", it will download a copy of your (encrypted) wallet from their servers.  Or, if you want complete control, you could use Mycelium and rebuild the wallet (after travelling) using the seed -- then it's just a case of hiding the seed somewhere.

Curious what on earth they think bitcoins are.  It's not like they're in your phone.  You aren't transporting them anywhere.

Yea I think the dollar and other fiat currencies have still got a long life ahead, though I think something like the dollar could collapse or lose a lot of its value eventually.
