Are you thinking that after ETH 2.0 is launched, the price will grow 10x? The market isn't like that especially if the market growth is natural. Unless ETH is greatly pumped, we will never see such huge increase in a short period of time, but if you look at its recent growth, ETH do increase in market value. I think ETH 2.0 is one of the reason why ETH market price increased.
So far this year, the ETH prices have moved upwards by around 400% and most of this price rise can be attributed to ETH 2.0. Some of the experts even claim that Ethereum looks overpriced at this levels. But I don't share the same opinion, since the current level is still around 60% lower than the ATH reached during 2017-18. But any claim of 10x sounds impossible for me, at least for the next 2-3 years.
