The four-point airdrop suddenly prompted a violation of regulations and was locked down. I really did nothing, no technology, no equipment change, purely manual. After thinking it over, it might be related to my participation in the trading competition. Initially, I only traded pepe and nft in the competition, thinking that sundog would be very competitive, so I didn't participate. After lunch, I checked the results and realized that participating in two tickets would not get me the overall leaderboard rewards and would incur losses. So I quickly joined, and in twenty minutes, I executed 130 trades, trading 200,000 sundog, all at recommended prices for buying and selling. The speed was very fast, and it was probably deemed by the system as a bot because of this rapid pace. What bad luck. I can take a break now; I don't know if the rewards will still be given. If not, I wasted three days of trading and incurred a loss of over $100.
