Exactly. You'll need to keep the money flowing by investing it into something that would generate you big returns over the long-term. Because, if you only depend on saving your money, you might lose the valuation of that capital because of inflation.

A wise decision would be to invest part of your capital into Bitcoin, as it is a deflationary cryptocurrency whose value is guaranteed to rise over the long-term. Thus, combining saving alongside with investing could be a great benefit towards preserving your financial future and avoid bankruptcy.

Nevertheless, always plan with what you want to do with your money over the long-term to become wealthy in the future. The easiest way would be to buy and hold cryptocurrencies, as well as gold to become financially free. Just my opinion.
