If you really like ETH, buy it. If no, another ALTS also great for investment, bullish probably would come soon, collecting every dips which come would be great.
If you think that the coin has a good potential, then why not? investing always depends on
how you understand the project and how willing you are to wait for the growth and success. It's
no longer a surprise if ETH will continue to rise, the bull momentum will keep coming back, buying
in each dip will give you the opportunities to collect and save more coins while waiting for your target.
It's important to set your expectations and allow yourself to keep holding until the time that the coin hit
the peak and bring decent profits to your investment.
