The pre-market price difference between Binance's Usual and Bybit is about 5%.
You just need to buy Usual on Binance spot and then short the same proportion on Bybit.
I personally opened a short position with 2x leverage on Bybit.
If both are spot, arbitrage would be better; the risk is that the pre-market on Bybit is futures. If Usual spikes, the contracts on Bybit might get liquidated.
