Can ETH boost to $5K?
its very possible for ethereum to reach that price my friend
but, it doesn't mean if we should move our bitcoin to ethereum buddy, not all but maybe a half
Possible or impossible, that prediction still an unknown result because we don't know what will happen.
I guess it will happen but there is no exact time when it will happen, we know that ethereum growth was its always depend on the bitcoin movement, especially at this moment ethereum isn't good for transactions due to the high fee like bitcoin.
You can't change bitcoin enthusiasts mind, they keep holding bitcoin whatever happen to the price because these two coins that you mentioned is good for storing value.
