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've got some ETH, I bought them around the same price as you bought them. What I'm doing is just holding them for long term and here I'm not talking about days,weeks or few months, I'm planing to hold them around 1-2 years depends how the price is going and I still wanna invest this months even if the price is a bit higher than what it was but hopefully it will go up. You can do the same or you can make your plan for how long to hold or what profit you would like to have.
