No transfer is needed: both positions stay on their exchanges until the prices converge. The funding difference on this pair is 0.000% per day, which the position collects while it is open.
For a spot–perpetual (cash-and-carry) trade, the best JCT route is to buy spot on Bitget and short the perpetual on Bybit: +0.32% gross, +0.12% net, with +0.030% a day of funding on the short leg.
Spot–spot JCT arbitrage (buy on Bitget, withdraw, deposit and sell on KuCoin) shows +0.13% gross right now. It only works if withdrawals on the buying exchange and deposits on the selling exchange are open, so check the D/W dots before moving coins.
Small JCT gaps usually disappear after fees, slippage and funding. Look at the Net column, the executable Depth and the spread history before trading: a gap that has been open for days is a different trade from a one-minute spike.
