Bee: I once read an article about Bonus Bonds that stated that if you have $10,000 invested in it the odds are you will win some prize every month...
This is an experiment I intend to try if I ever have a spare $10K...
I know someone who had over $10k in them, and they didn't win every month. I believe the winnings worked out at less than 2% over the year, which is a lot less than you get in the bank. I told them that they maybe better off to put the money into a high interest bank account and buy a lotto ticket each week from the interest, and they would still get some interest left over too.
I have $500 in bonus bonds and last month I won $60, but was the first prize in years.
