There are so many options to choose from especially with young developing minds and childish wants and needs. Most people the same age as you would say "I would spend it on a big house and big car!". But is this sensible option?
If another bank crash does happen...(it may be possible. You never know.)..There would be no money to sustain it and may end up being taken away. £100billion is a lot of money and to have that going down the drain eventually is almost inevitable.
Let me know what you would do by commenting down bellow.. :)
