There aren't many options with the cash.
We used to see interest rates adjusted upwards to cool a booming economy, but not anymore.
Still, I'd rather put my cash in a savings account that earns the highest interest I can find (currently at around 2%), or short-term FD. Short-term bonds, whether corporate ones or government ones, aren't that bad too.
These are at least better than getting locked up in money-losing investments.
Or maybe start a business?
