If you’ve decided to play with contracts, you need to clearly understand the logic behind exchange contracts! Going to zero is the norm... When you’re playing contracts on any exchange, if there are no users betting against you, then your opponent is the exchange’s backend. The exchange backend has multiple systems, showing different backends for different customers, and it can clearly calculate directional profits! That’s why I’ve always advised against playing contracts... Binance is okay in other aspects, but I’ve always been strongly against their leveraged contracts.
