I am a college student looking to make a buck every once in a while trading crypto (mainly BTC). My portfolio is $500 of my savings so nothing big really. This is like a pilot project where I get to learn what is what and see if I can trade. I am considering going full time during summers and hopefully after finishing college if summers will have spared me. The question I am constantly facing is, how do you know when you should (or have to) sell? When the price is rising, I don't want to sell because... greed ––tbh. But again when the price is dropping, I don't wanna sell either... sometimes the price might be lower than when I bought. In general, I am bullish that the price will eventually rise and I will make a killing, so no need to hurry. But again, I don't want to be a hodler; I want to be a trader. How do you guys know when to sell?
