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.
We have not even began to see the main bull run and you are already talking about taking profit, I don't think it's a good idea to take profit now unless you are in need of the money and want to use it for something urgent.
We are just getting to the beginning of the bull run, and I can assure you that the price of bitcoin and ethereum will get to a very great height by the end of the fourth quarter of the year. We might see the price of bitcoin getting to $10000, and also see the price of ethereum getting to $500, so no need to rush.
