Right now, about 30% of my 2 Spot-Futures Arbitrage Bots wallet is in USDT and 70% in ADA and XRP.
Spot-Futures Arbitrage profit doesnt really affected by the token price, either it increase or decrease. It mostly comes from funding fee, which is less related to the price. If XRP token price surging 30% , you wont have a 30% profit from that movement. Same case if XRP price decrease 50% , you wont have a 50% loss with the Spot-Futures Arbitrage Bot.
