These days I've been watching whale wallets again, and the more I look, the more I think "copy trading" is really quite mysterious... The same large transaction looks like building a position, but actually they might have bought spot and used futures to hedge with a reverse position, insuring against fluctuations, keeping a very calm mindset after hedging; when I, a FOMO warrior, rush in, I end up just helping them lift the order and catching the waves for them. Especially recently, the "profit stacking" from pledge/sharing security setups has been criticized as a copycat scheme, which makes me more cautious: the more complex on-chain actions are, the more likely they are for risk isolation, not just bullish speculation. Anyway, I now tend to think first: are they adding to their position, or transferring risk elsewhere... What I’ve learned isn’t techniques, but not to treat others’ positions as your own beliefs.
