Large funds entered the ETH market last night, and the "trend" reversed as soon as it broke through 3250. This trend is currently only relevant for this week and the week leading up to next Thursday. The weekly MACD is preparing to turn upwards, and the 10-day moving average has also shown signs of support. The next high is expected to be around 3600. Therefore, shorting at 3600 offers the best risk-reward ratio. Some are considering going all-in on shorting around 3400, but this is not recommended. If 3440 is broken, the price will likely surge towards 3600. 3520 and 3550 are weak resistance levels, while 3660 is a strong resistance level. The next resistance level around 3600 is 3588, and the resistance levels between 3600 and 3660 are 3626 and 3646. If you short above 3588, the profit potential is quite good.
