What needs to be noted at present is that both Bitcoin and Ethereum have stood firm at TD13 in the 4-hour chart. The emergence of this indicator also means that a rebound is needed to repair sentiment in the future. As for the fact that the currency price has not rebounded yet, it is mainly because after the key support of 3,300 was effectively broken, the bearish sentiment of the market trend line began to increase, which led to the market's selling sentiment severely crushing the bulls.
