I think the idea that money in a bank is not safe is a common fallacy amongst us in the Bitcoin community.
In the UK, we have £70,000 protected by the FSCS should the banks fail. That is a hell of a lot more secure than stashing cash under a bed or Bitcoin on a hardware device. Don't get me wrong, I believe Bitcoin will be a massive force of change, but not for the reason that banks are unsafe - more that they are simply redundant in a developing world of Cryptocurrency.
