Ig you are talking about bitget trading events, normally I saw these events will give you a time limit and top volume scorer gets rewarded. For this reason lot's of flash traded are done, you look normally making profits 2-3% from every trade while keeping up the leaderboard/on the trading competition it's hardly I've seen anyone can pulled off.

Lot's of my Friend trades on Binance , for their trading competition. For just rewards money they wash their trading fees. Even though they do flash trades they can't keep up with the leaderboard sometimes
