Whenever you think that that is a good timw. Its very hard sometimes to recognise a point of time. Which time would be better for selling in high time of the market. So whenever you think that the those coins are profitable to you start selling the. Got me I made a hole strategy for that let for me the best point for market is when bt is around 11-12k zone. So when ever market enter that moment I start selling. And I will start sell in parts. Now if the market came from 14-15 kind points I don't gave a regret. That's it. So don't be so greedy that have to missed the train.
