This trader has made a profit of $40000, with the capital investment of $45000. This too is achieved using the stablecoins USDT and USDC. In between the trader has borrowed $40500 and with the swapping between exchanges has netted the profit of $40000 after paying a transaction fees of $2000.
First of all this guy starts with a large amount himself, he then tops that up with some more borrowing and technically takes advantage of the price disparity between USDC, ETH and USDT. In this process ETH showed an uptrend, so the guy got lucky as hell.
After this crazy bump and profit, he sold out ETH -> got USDT then back to -> USDC, payed off the loan and retained the remaining profit.
Overall, this shows strategy combined with a lot of risk by borrowing and starting big and also getting lucky. Not so reproducible after all.
