What is the difference between isolated margin and cross margin in crypto?

[Fidelia]

Just when I am struggling to understand what Margin Trading is. Just found out that there are two types of margin trading. One is Cross Margin Trading and the other is Isolated Margin Trading. What is the difference between the two. Can one help to explain with illustrations?

The difference between isolated margin and cross margin in crypto is mainly in collateral, such as isolated margin is only for one trading position, so the risk is not spread to other positions. While cross margin uses all margin balances for all positions, so the risk will be spread to all positions, cross margin also has a higher risk tolerance than isolated margin.
