No matter how old you are, you should learn to manage your money. The key depends on your own income and monthly expenses. You can't take out as much as you want to save and use every month. At present, there are many balance treasures for financial management, and a little interest can be spent at any time every day. You can also make money from small change. If you want to save money regularly, you can buy a regular deposit. If you want to protect your capital, you can buy currency and bonds. Pure debt is a little higher than monetary income, and the risk is a little higher.
