When low-probability events occur continuously, it is highly likely that a key factor in the market has changed. The current market situation resembles the sideways correction in February of this year, with weekly candlesticks forming cross stars for several consecutive weeks. More importantly, the altcoin market has retraced to the halfway point of the weekly chart; generally speaking, altcoins will decline first and then accelerate the decline together with Bitcoin. Currently, the overall altcoin market appears to be on the verge of collapse, so the best strategy right now is to short altcoins at highs (for rebounds below 30 degrees) and long Bitcoin at lows.
