Take your profit it is the most important thing who ever that is a trader into cryptocurrency especially have to understand that you don't need to be greedy in any of your investment because sometimes greediness is one of the things that affect anyone who is into cryptocurrency investment especially someone who is into bitcoin, even in a day trading you don't need to be emphasising on a particular point that you will make a profit, it's better you make a small profit than losing everything
as many have said a profit is a profit its better to be a profitable trader than just holding on for too long due to greediness and then lose that profit that don't get realized its gonna be silly to lose profit just because we are holding too long having too much high of an expectation towards the bullrun but sometime a trader or investor also have their share of reason why they keep holding onto their investment as long as it is a good reason then it make sense for holding despite already hitting all time high.
but many times people are just get too intrigued with the profit that they might potentially earn from trading or investing that they decided maybe holding might be a good way to further increase the profit not knowing that usually market dumping can happen in just a blink of an eye then the market become bearish, remember that pumping happens slow and dumping happens fast, because with pumping people are full in doubts whether the price gonna keep going up and with dump people are so fearful of losing their money so they cut loss or dump earlier.
