Considering that BTC falls below 6k, a further fall to the next levels at $413 and $366 is expected. $366 is supported by the yellow 377-MA and also it was the lowest point that Ethereum hit this year.
On the other hand, if BTC rebounds and regains the $6500 levels, we expect ETH to retest the trendline, aiming the 61% Fib level at $546.
A buy range would be at $450-$460, with stoploss at $430. After breaking $500, ETH will target the $520-$530 levels where lies.
