I know how premium bonds work… It is a tombola raffle, all the prizes will be won every month. It is a random draw, each bond has the same chance of winning as any other. If you hold maximum amount bonds you have a 49999 more chances of winning than if you only hold 1 bond. Winning isn’t guaranteed.
I’ve a good idea of the basic game I’m playing with my money and I’m lucky to do what I’m doing. It has taken a fair amount of restraint to save up.
I won’t always win and I’ll try to minimise my losses. Premium bonds are my low risk form of gambling.
My current thinking is not too reinvest pb wins straight back into your incomplete holdings as you will lose out on nearly 2 months of interest or just general enjoyment of spending the win.
All pointless musings anyway and my interpretation of luck, winning, losing, profit and loss will be different to someone else’s.
