Like renting a bank safety deposit box.
Probably makes sense.
Not if what you deposit in the box will be worth less than when you take it out. That is basically what you are doing if you save a fiat currency at ANY rate that balances out with inflation to less than zero.
You pay the 'fee' for renting the box and your cash gets eaten up by inflation.
Yep, just about the same.
DOH!
