Where are there so many techniques? It's just about calling long when it rises and calling short when it falls. If it rises for a long time, you just need to post a few more short calls; if it falls for a long time, you just need to post a few more long calls. Think about it, is it really like that? If you don't dare to reveal your actual trading, just treat it as nonsense. #加密市场回调 $BTC
