Recently, looking at those "coincidental transfers" on the blockchain, many people immediately say it's the team washing coins or insider trading. Actually, I prefer to break down the path first: which liquidity pool it came from, how many intermediaries it passed through, whether it's the same batch of gas / batch sent within the same period, and finally which type of address it lands on (exchanges, bridges, contracts). Others think it's some mysterious big shot controlling the market, but in reality, many are just scripts running batch transactions, collecting testnet incentives conveniently, plus the expectation of points making everyone fill in the gaps… As for whether the mainnet will issue tokens, I don't know either. Anyway, my usual approach remains the same: record addresses, track by groups, cut losses when needed, and don't be led astray by "coincidences."
