I think the price of ethereum will return to such an expensive price when the bitcoin price can recover at least back to the price of $15k then that will make the ethereum price to the price of $ 200 again, so be patient and wait until the ethereum price reaches its target.
for ethereum to reach $ 200 it might happen in some more improvements. but when you talk about bitcoin that reaches $ 15k it is far from predictable. take a look at the market ability now, where are the prices of bitcoin and ethereum.
Everybody knows that the market is unpredictable. Thus, it might happen that Ethereum can hit 200 bucks. It will be a norm, as the cryptocurrency is very volatile, and ETH has really great potential.
