i am looking for arbitrage opportunity, buy USDT cheap sell for FIAT high. the currency [ nigerian nira] is quite unstable there is the official bank rate, blackmarket rate and rate on p2p platforms. i saw an opportunity on kyberswap last year when the spread was decent and the fees would also be covered with that spread, but they adjusted the rate and i have been looking for DEX's that i can replicate such opportunity. any suggestion or aggregators i can watch and compare. THANK YOU
