Recently, someone has been watching whale addresses and trying to follow their trades.

I think there's no need to rush; it's really important to distinguish whether they are building a position or hedging.
On-chain, it looks like "buying," but on the other side, they might be opening shorts in perpetuals or locking in risks in other pools.
If you just copy their trades on the surface, you'll only catch the surface, and when volatility hits, you'll have no one to blame but yourself.
I thought a big holder continuously adding to their position meant they were about to take off, but upon checking, they were simultaneously maxing out their collateral ratio and still earning from stablecoin yields, which clearly looks more like they’re using volatility to exchange for cash flow...
Recently, RWA, US bond yields, and on-chain yield products have been compared a lot, but honestly, the more "stable" things seem, the easier it is for people to let their guard down.
Anyway, I prefer to go slow, confirm the logic before acting, and avoid self-deception.
