Saving means easier access to spending it. But when you invest it chances of earning more out of it and holding it for some time before you can spend it
well, when you invest chance of earning more increase, but don't forget equal chance of loosing will also came along with chance of earning.
when you invest you can face either profit or lost.
However that can be an exercise for anyone trying their hand at investing in any thing in the first place. Thought it is not encouraged to experiment in this manner but losses will make you learn from mistakes, and then chances are you might not make that mistake again.
In any case if you are not confident about some investment you should not do it and so taking chances are good for experiments - better done with smaller amounts of money.
