Timing the market vs. time in the market with Ethereum?

So I was holding Ethereum from the beginning of the year until it recently hit near the ATH in May. Had some medical issues where I had to sell all of it but it helped me pay all my bills. That being said, I am now financially stable again and want to hop back on the train.

This time I am going to HODL and not sell for years while continuing to contribute. There seems to be recent hype that is driving the price which is typically followed by a dip. This time just feels different and I feel like we are going to have a new floor around $3,500. If you were in my shoes given this information, should I wait for a slight dip or just get in now before it continues to trend upwards?
