I have invested in ETH when it was $105. Now it's $176. Will it be a good idea to take the profit now? Or I should hold on for better profit which may lead to less profit too

Suggestion is appreciated.
I suggest getting those profits already, for you do not regret what you have profited right now. Once the value of your ETH gets down again then that's the time you will regret and for sure will also lead you to make panic selling which is not good. So, for me, it is better to get your profit now.
