The recent market situation feels like "no one is willing to buy" again, liquidity dries up, and so-called bottom-fishing often turns into catching a flying knife. Honestly, it's about surviving first and then talking about other things. I’ve backtested a bunch of simple rules, and what can really save your life isn’t how smart you are, but not fully invested, not stubbornly holding on, and keeping some cash to wait for the volatility to subside. Recently, the "compound returns" from pledging and shared security strategies have been criticized as a trap, and I’m a bit worried too: the longer the chain, the more a problem causes a chain reaction. It looks pretty good normally, but when things get tense, you can’t escape even if you want to. Anyway, I’m now more concerned about whether I can withdraw at any time, rather than earning that little extra.
