Some people may feel that the volatility of Bitcoin and Ethereum is too high, making short-term contracts difficult, so they switch to long-term contracts on altcoins. As a result, the altcoins did not rise, but instead fell. Congratulations, you may have been deceived. The funding fees may be giving you a headache.
In fact, trading altcoins in spot markets is more reliable. In the short term, there will definitely be a large drop. At that time, if you are trading Bitcoin and Ethereum, the worst that can happen is that you may have to cut your losses; you won't get liquidated. However, if you are trading altcoins, the probability of liquidation is much higher, and the drop may exceed 50%, with almost nothing able to hold its ground.
