I don't know. There are three ways this could go: Life proceeds normally The child learns a lot from the experience of raising money for this invention, along the way gathering all sorts of experiences that are valuable in the working world. The child (Well, parents until $age-of-majority) get 30$m with which to improve the child's life. Either of the secondary options are useful. You're viewing the value of money and survival as the primary goal. The child could already be set for life with that depending on the earning of the parents and their pensions, etc. Either of the two latter options provide unknown gains and losses to the child, depending on what you value more. Note that this excludes negotiating a better bid with another company.
