Just now, my phone popped up a red dot saying "Whale address added to position," and when I clicked in, the trading was quite fragmented... To put it simply, before copying trades, you need to clarify whether they are building a position or hedging; otherwise, you might think it's a "signal," but it could just be them opening a counter-position elsewhere to lock in risk. The simplest way I would check is: whether they have synchronized moving margin/stablecoins into the contract, whether spot and perpetual are in the same direction, and whether the positions are being gradually built in batches. On-chain data is actually more straightforward than looking at candlestick charts; pulling up the address's fund flow makes it clear. Recently, modularization and DA layer discussions have heated up again, developers are excited, users are confused... But during these narrative phases, whale operations are more likely to "look like" something; in reality, it's just arbitrage or risk control. Stay calm first, don't be a plot enthusiast.
