But banks offer better protection for my money than can be afforded in a home settings. Quite the opposite with BitCoins. My TrueCrypt volume with keyfiles that I keep on my person and in a safebox with my BitCoins inside is far superior to... well... ANY internet-connected service.

Possible shorter version of events:

People left their money with some guy on the internet.

He promised them he wouldn't steal it.

But then he stole it.

But there's no reason to leave a quarter of a million dollars in BitCoins in an untrusted 3rd party's hands. Unless you're lazy or naive. It takes almost no effort to transfer them to your own wallet which can be trivially encrypted or stored on a device unconnected to the Internet.

but there's no reason to do it all at once. if you are trading 1 btc for money there should be an automated way to do the transfer in increasing steps, after each of which the other party would reply - so transfer 0.0001, 0.001, 0.01 etc. til you are done. You wouldn't lose much, and you could vary the rate depending on how much you trusted the other party.

Yes, it is: assuming you use client side encryption, an online storage company never needs to know your secrets. It's the difference between a trusted and untrusted third party.
