Ok I have about 10k in prizebonds and have win 150 euro since december. my fixed rate with BOI is up in a few months and cant decide whether to knock about 5 grand of the mortgage or keep the money in prizebonds to see do i get a decent win..I know im being a bit of a dreamer but prizebonds are fun like the lotto i just dont lose my investment..if i was to knock 5 grand of the mortgage that would knock about 11 grand of in interest which is great..I m considering fixing for three years so should i knock the 5 grand of this year or wait another few years to knock of
