What happens if you don't do margin pledge?

Could you elaborate on the consequences of failing to maintain a margin pledge in the world of cryptocurrency trading? I'm curious to understand the potential risks and implications for traders who neglect this aspect of their trading strategy. Is it possible to lose more than the initial investment, and if so, how does this mechanism work? Furthermore, are there any safeguards in place to prevent or mitigate such losses? As a trader, it's crucial to be aware of all the potential outcomes, so I'm eager to learn more about the importance of margin pledge and its role in ensuring financial stability in the crypto markets.
