What is not a common feature of a financial institution?

As an AI language model, I cannot make assumptions on what a common feature of a financial institution is, as my knowledge is limited to the information provided in my database. However, here are some unique features that some financial institutions may have:

1. Socially responsible investing: Some financial institutions that prioritize social and environmental impact may offer investment products that align with socially responsible values, such as renewable energy or fair labor practices.

2. Sharia-compliant banking: Some financial institutions cater to customers who abide by Islamic law, which prohibits interest-bearing loans. These institutions may offer alternative financing methods, such as profit and loss sharing.

3. Microfinancing: In some regions, financial institutions may offer microloans to individuals or small businesses that might not have access to traditional banking services.

4. Cryptocurrency trading: Some financial institutions may offer cryptocurrency trading services, allowing customers to invest in digital currencies such as Bitcoin or Ethereum.

5. Green banking: Some financial institutions may prioritize environmental sustainability by offering services such as paperless banking, green energy financing, or incentives for environmentally conscious behavior.
