Lately, I've been obsessively watching whale addresses... To put it simply, before copying trades, you need to figure out whether they are building a position or hedging; otherwise, you might think it's a "buying rush," but in reality, they might be using you as liquidity padding. Especially now, with interest rate cut expectations fluctuating between hot and cold, the US dollar index and risk assets are often discussed together as rising or falling together, which can easily lead emotions astray. My noise reduction strategy is very crude: only watch the rhythm of the same address over several consecutive times (whether increasing or decreasing positions follows the same logic), and treat other group screenshots as noise. If I miss it, I miss it; anyway, I've been educated many times already.
