Building wealth through passive income streams is a smart financial strategy that can provide long-term financial security. Passive income is money earned with minimal effort through various ventures such as investments, rental properties, or online businesses. Here are some ideas and strategies to consider:

1. Real Estate Investments: Investing in rental properties can generate consistent passive income through rental payments. Additionally, real estate appreciation can build wealth over time.
2. Dividend-Yielding Stocks: Investing in dividend-paying stocks can provide a steady stream of passive income. Companies that have a history of paying dividends can be a reliable source of income.
3. Creating Digital Products: Developing and selling digital products such as e-books, online courses, or software can generate passive income through ongoing sales without the need for continuous effort.
4. Peer-to-Peer Lending: Participating in peer-to-peer lending platforms allows individuals to earn interest income by lending money to others, providing a passive income stream.
5. High-Yield Savings Accounts: While not as high as other investment options, high-yield savings accounts can still generate passive income through interest payments on savings.

It's important to note that building passive income streams requires careful planning, research, and often initial investment of time and money. Diversifying passive income streams can also help mitigate risk and ensure a more stable financial future.
