It is difficult to predict the price if it will reach $ 100,000 per ethereum actually it will take many more years to reach it there is a possibility that it will reach if many rich people invest in ethereum or even the richest people in the world but many more years spend and projects to reach that price.
It is hard to predict but there is always possibility that ethereum will reach $100k but the fact we see from other top coins before they reach its level now. They passes many months and years before they achieve their level today. What we need to do is just check or follow it from to time in order to be updated on its value and also be patience in holding until you achieve the amount you've want.
