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.
Suggestion is appreciated.This decision is purely on you! The profit you made is pretty good.
Do not forget, right now btc and eth are raising, the alt season no one canceled and one day it will come
If you are for the long term in your position, just relax and watch. If you want more profit, check the alts, which ones you can buy and diversify your ETH position.
