Let's not fool ourselves. Banks are infinitely safer at this point in time. Sure, we can all spread FUD about how evil and insecure they are, but in a bank, our money is Federally ensured regardless of the circumstance.
Tell that to Cypriot or Greek
My apologies, sometimes I forget this is a global forum.
I cannot speak for everyone on earth, but in the United States, your money deposited into banks are Federally ensured (up to $250,000 I believe). This is infinitely more secure than the 0 insurance associated with a Bitcoin wallet.
And when the banks introduce negative interest rates to save themselves again?
I was not aware this has ever taken place in the US? Of course, there were a lot of banking/credit issues that led to the Great Depression in the 40s, but in response a lot of regulations and safety nets were added in order for the public to regain faith in the banking system. And I do believe that there has not been anything in the form of negative interest rate since that depression.
You are correct - but negative interest rates are spreading across Europe - and there has been much talk of "banning cash", from both the European and American sides of the Atlantic. It is a real risk - as is inflation. Of course BTC hasn't shown that is an effective hedge against inflation yet, even though it was designed that way. I can tell you this much however, fiat money kept in a bank account deflates more than what you earn in interest.
