September is a dangerous month for three reasons. 1. The cryptocurrency market is now completely in sync with the US stock market, so we'll have to watch how the US stock market moves. 2. The end of the third quarter is when traders adjust their portfolios. They need to present financial statements to investors, so they need to find ways to make them look good. Therefore, they'll close out their positions that have seen significant gains in September and hold onto their profits. ETH's surge this quarter has been incredibly rapid, and the corresponding US crypto stocks are in sync. 3. Because of the previous reason, most retail investors will be cautious and wait-and-seek in September. Lock in most of your gains. If the market continues to rise, you'll lose some of your gains. However, if it retraces, the losses will be much greater.
