I used to have thoughts similar to yours. But after thinking it through, I realized something was off. 1. Perpetual contracts, as a type of derivative, are not suitable for trading targets with predictable trends. Let me give you an extreme example: say one day there's an IDO or NFT launch, and everyone knows there’s going to be a gas war. Then retail traders all rush to long gas, but end up paying a ton of funding fees to the shorts. The long positions might profit, but the fees eat it up, making it pretty pointless. 2. Secondly, perpetual contracts are also not suitable for targets with unfair pricing. Another extreme example: if I secretly set up a huge long position, then go on ETH and spam dust transactions to push gwei prices up, the shorts would be in a pretty bad spot too.
