A lone trader lost more than $11 million on a single futures trade involving Theta Networks’ THETA tokens as the price jumped 18% in 24 hours. This is such a huge amount that I won't even know what to do if this happens to me. But ofc it will never happen to me since I don't even have that much money in the first place.
If you are not familiar with when and how liquidation happens, according to coindesk:
Liquidation occur when a trader has insufficient funds to fill a margin call – a demand for extra collateral by the exchange to keep the trading position funded.
