Cryptocurrency is really unpredictable. It can go to peak at this moment and drops $4,000 tomorrow. It can also be stagnant for the whole month or so. In this i learned that you shouldnt speculate much about its price bit rather put some goal price or margin where you sell it whether you like it or not. If you dont needed the money yet then its better because you can wait longer than others. With this you cant avoid greediness and earning depending on your goal price.
Yea you're right anyone. Who is trading is meant to have their goals and once you have accomplished those goals it's then up to you to decide on whether you want to continue or to first take a quit and withdraw what you have got already. Mainly what I do is that I don't speculate much on what the price is going to be, I set my target low and once I have accomplished that, I look if there is still any possibility for the market to go further and if there is, then I will continue to where it stops before taking a quit to get back in later.
