"Do you think ETH will hit all Time high (ATH)?", I would take it as a goal that will definitely happen in the future. The question would be better when this will happen.
Ethereum tends to rise in price without the growth of bitcoin, but it will not be in this case. In the past, ETH reached its peak at a time of Bitcoin price growth. So, when BTC will reach a new "all time high", the time will come for Ethereum.
