Often times, everything goes up or down with BTC, some alts with delay. The focus with ETH is on their scaling, smartcontracts work and get more and more usecases. But tx with smartcontracts can be very expensive, so on UniSwap you exchange $100 worth of tokens but pay $50 in gas (network fees) if you are unlucky. More tx, higher fees.
No one can predict that either the front with 100% probability. Especially when it comes to cryptocurrency. I remember how all Bitcoin predicted high stable growth in 2017, and he fell. Then everyone started saying that this collapse. a Bitcoin has grown.
