What kind of trading do you prefer?. In trading, we have spot trading and futures trading. In the spot, you are willing to hold your assets for the long term. In future, you make a short trade depending on the time frame, 1 hr, 4 hrs, 1 day, etc. Every time you commit a trade don't become greedy or too much handle by your emotions always stick to the trading plan and set a TP and SL. I guess this topic must related to the Trading discussion.
Future trading can be viable also for longer trades. There are perpetual futures, or you can roll your position on longer future.
But you are right about the rest of your message: don’t fall in love with your position and be ready to take action when you touch a SL (Stop Loss), being the most important one.
