well, eth only needs a 30% increase to reach the $4k price tag. I recommend buying and holding eth because the price of eth can still go higher. After upgrading to eth2.0 I believe the price of eth will reach the new ATH.
The London hard fork for ETH 2.0 has been going on for almost a week and the price increase on ETH is very clear indeed, but if the market situation is still in bad shape, then the 30% increase will be difficult to achieve from now on, unless the market can always be good until the end of the year, then ETH shouldn't take long to be at $4K.
