It looks quite difficult to get into that phase again, now we can see where BTC dominance is already very large in the market, I think ALT season will come when BTC dominance decreases maybe in the range of 50%, so you can estimate if BTC dominance decreases meaning ALT season will appear soon.
< 50% would be a good indication that alt is slowly getting back and investors are coming in the market again. But if you look at the dominance today, alt are still suffering and bitcoin is still as strong as ever. There were times that it crosses 70%, as and far as I can remember that's the biggest dominance we have ever since in recent years.
As far as the price of Ethereum goes, the charts look solid and it could be a good indication that at least reaching $200-$300 at the end of the year is possible. So let's see how it goes, I'm seeing green today and hope that it will continue to at least touch base $200 in the next coming weeks or before the end of the month.
