For me, don't invest it. There are many things that people have bought in the past, driving them to absurd prices, not because they did anything useful or produced money or had social value, but solely because people thought they could sell them on to someone else for more money in the future.
But investment that I think it is very important for the future, because we dont know what will happen after we are old later and no longer able to work for money, because when it was the money investment we will be useful for us to wear after the old, or we can make the as a legacy to our children later
