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.
Its better to take profit while it takes a massive gained because as market price always fluctuating we dont know if it will rise or down in the future. Better to secure you capital first than wait for the long run and get less profit.
Well,you are in the best position to take that decision because you know what you want to achieve, it all depends on how you project your investment either long or short term, but you can take out your capital and reinvest the profit if you don't have the patient.
