Answer:
I would suggest that Nick invest the money he owns, or part of it.
Step-by-step explanation:
If Nick invests his money, he can multiply that money in a short time. Which will be much better and safer than just saving the finances without the possibility of increasing them and at the risk of spending them.
I would tell Nick to research on how to invest, which markets are appropriate and most profitable, how much money he could invest, and how long the return on profits he would need.
By investing, Nick will have full control over his investments. Once you have done your own analysis.
