The Block reports a trader netted about $1.28 million on Papertrade, a new exchange offering 1,000x leverage. Papertrade copies its prices from Hyperliquid’s order book, and the trader simply moved that order book — buying and selling large amounts of ETH on Hyperliquid itself. Papertrade said its launch trading limits were too loose and is tightening them.
