It is unrealistic to talk about reducing expenses under the current conditions, and there is not much to save.

If you want to open source, the necessary investment is ok.

If the risk is low, deposit it in the bank, and then study how to deposit it every day, and get an extra yuan (er, maybe ten yuan)

It is better to buy government bonds.

But none of the above methods is very good, because-the currency is always depreciating.

In order to cope with the risk of currency devaluation, we should have no cash on hand.

In other words, invest as much money as possible and use more money in the future.

Specific operation:

Get a credit card, then spend as much as possible, never use cash, and make full use of the interest-free period.

There are two advantages:

First, enjoy the interest-free period, so that your cash is equivalent to interest, which may bring 1% income a year.

Second, I have accumulated my own credit, and I can use my credit to borrow from the bank when I need it in the future, which partially solves the problem of insufficient venture capital.
