Surely the odds are the same for a £25 investment as for a £25,000 one. Of course the chances of a win are higher for a larger holding. Don't forget the 3.3% is tax free as well. The first eligible draw for my bonds was in January, and if you assume that I will pick up another £50 before the end of the year, then I will still be down on the interest I could have earned.. But I wouldn't have had the fun of checking every month to make sure that I haven't won £1,000,000. Also, I wouldn't have been able to start this thread, and as I mentioned, I have found the replies very interesting and illuminating. When considering replies, you need to take into account my personal situation. I'm a rebellious prepper, who is over 80, and because I decided to opt for an offgrid lifestyle, I don't really want for anything. Well maybe some alloy wheels for my Volvo daily driver.

I appreciate the need for emergency fod supplies, but I already have 3 removal crates full of tins and pasta ( those are the 3 foot long crates), and those include sardines, salmon, tuna, and varieties of meat, as well as vegetables and soup. I should probably buy some Bitcoin right now, as I suspect it will drop a bit further, and then shoot up. However, I try to deal in domain names to build my Bitcoin investment. I can get a much better return on my investment by buying classic Volvo cars. I paid less than scrap value for Cinderella ( the volvo in the image), and it probably worth around £1,500, because it is a bit of a rat rod, but it is a great daily driver. It only cost £50 to pass the government inspection a couple of months ago, as it didn't need any repairs. Not bad for a 1988 car!
[edit]
I forgot to mention that I still seem to be on the good luck roll. Somebody had left £4.71 in change in the do iy yourself checkout at the supermarket. Not a lot, but all these bits are mounting up.
