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.
So bad if you still HODL your ETH during last week. Better to sell on the top but the problem is to catch the top of the trend. Holding till making a profit can be a pain if you have less experience in this sector. I personally sold my holding at peak and bought later for a cheap price. Suggestion is appreciated.
