From the surge in technology stocks to dealing with the precarious nature of cryptocurrencies, the modern economy presents not just a myriad of opportunities, but also a series of challenges. Thus, it becomes paramount to understand how to engage in astute investment strategies. Here are the top 10 smart investment strategies tailored for the rapidly changing and dynamic modern economy.

1. **Diversification**

This is one of the most conventional and popular investment strategies. By distributing your investments over a variety of different asset classes such as bonds, stocks, real estate, or commodities, you can mitigate risk. The volatility in one asset class could be offset by stability in another, safeguarding the overall portfolio from extreme fluctuations.

2. **Investing in Stocks**

Given the current low-interest-rate environment, investing in stocks could provide better returns than most traditional savings accounts. Despite the risk of volatility, a well-informed investment in stocks often yields substantial returns in the long run.

3. **Consideration of ETFs and Mutual Funds**

ETFs and mutual funds allow investors to purchase a diversified portfolio of investments in a single transaction. This reduces the risk and time consuming nature associated with individual stock selection. It’s essentially diversification served on a silver platter.

4. **Automated Investing**

Also known as robo-advisors, automated investing takes charge of portfolio management for you, typically by investing in ETFs. Based on risk assessment of your financial situation, robo-advisors can offer a simple and low-fee alternative to traditional advisors.

5. **Dollar-Cost Averaging**

This strategy involves investing a fixed amount of money at regular intervals, regardless of the market conditions. Dollar-cost averaging, over time, reduces the impact of market volatility on investments since you’re purchasing more shares when prices are low and fewer shares when prices are high.

6. **Investing in Real Estate**

Investing in real estate can provide monthly rental income, appreciation potential, and tax benefits. With multiple means to invest, such as REITs, rental properties, and crowdfunding, real estate investment should inevitably be part of your portfolio.

7. **Investing in Cryptocurrency**

Regardless of controversies and unpredictable volatility, the era of digital currencies is upon us. Cryptocurrencies like Bitcoin and Ethereum have shown significant growth over past years. While crypto-investment can be risky, diversifying a small portion of your portfolio into it might lead to remarkable rewards.

8. **Impact Investing**

This refers to making investments in companies or funds that aim to generate a measurable social or environmental impact alongside a financial return. This societal and financial dual objective makes impact investing an appealing option.

9. **Value Investing**

Popularised by the legendary Warren Buffett, this strategy involves investing in undervalued stocks that are trading for less than their intrinsic values. A bit of research and patience might just land you a fantastic deal on a great asset!

10. **Peer to Peer (P2P) Lending**

P2P platforms allow you to lend money directly to individuals or small businesses in return for a agreed-upon interest rate. An innovative way of investment, P2P lending can be a profitable way to diversify your portfolio.

Navigating the choppy waters of today’s economy challenging, but a strategic approach to investing can minimize risks while maximizing returns. As always, before committing to any investment strategy, it’s crucial to assess one’s own financial situation, risk appetite, and long-term goals. Happy investing!
