The legendary 'Rolling Brother' who turned $125,000 in principal into a long position on ETH was liquidated during the market crash last night and this morning, with only $70,000 left in margin, turning a profit of up to $9.19 million into a loss.

The myth was shattered in just one night. This 'Rolling Brother' story of sudden wealth had inspired countless traders, while his liquidation outcome provided a lesson in risk management worth tens of millions of dollars for all leveraged players. There is only a black swan's distance from heaven to hell.

This story perfectly illustrates the brutality of high-leverage trading: you can be right a hundred times, but as long as you are wrong once, you could end up back at square one, or even lose everything. In the end, the market will teach everyone to have respect in the most painful way.
