As much as I can tell from my own ignorance. Since you are buying during the 3k price, I think it is better to hold now. Because it is the 2nd biggest coin in the market which will take less time to recover. I can suggest you something if you have more money you can dip which will be good for you. And if you have more patience then you Wait for the market pump it will do you much good and profit.
Yeah, since the OP bought ethereum at $3k he shouldn't be disappointed, so I also think he should be patient and hold. Today the price of ethereum was around $2700 and only $300 increase would have allowed the OP to recover the loss.
Currently, the price of Ethereum is very low, so if you buy and hold Ethereum, it will be possible to make a good profit. However, try to invest what you can afford to lose so that you don't get disappointed if the price drops and you can hold patiently. The OP, wanted to make the wrong decision, he would have faced a loss if he had sold the Ethereum. OP I would advise you to try to invest what you can afford to lose, otherwise face losses.
