Currently, my three mid-term short positions are in BTC/ETH/BNB. I find that trading mainstream coins with mid-term trend orders tends to be more profitable because the battle between bulls and bears is more balanced, leading to higher certainty. However, with other altcoins, it’s harder to grasp the entry points for short positions; during a downtrend in BTC, going long on quality altcoins often goes against the trend. Short and long positions can be stopped out suddenly when I wake up. Therefore, I should focus on mainstream coin contracts and spot trading.
