I looked at the rebound of $BTC , the second wave trend fell to 60,000, currently rebounding to a maximum of 76,000, a rebound of 26%. Many altcoins are still unable to outperform BTC during the rebound; they fall even harder when the market drops. I previously shared an investment perspective: the investment risk of many altcoins is currently greater than that of contracts. For instance, during the recent sharp decline, if you try to bottom fish with altcoins, it's better to use low leverage to go long on BTC, which actually has lower risk and greater potential returns. Many people have clear stop-loss points when trading contracts, but buying altcoins in the spot market can easily lead to self-deception, buying more as prices drop, continuously averaging down without setting stop-losses, believing that spot will eventually rebound. The result is often being stuck with losses over 80%. Therefore, do not hold biases against contracts; using low leverage with BTC or ETH is much less risky than trading altcoins.
