I don't care about the short term stuff. It's all too complicated anyways. I just like to keep it simple and hold!
Those day/week traders are making good money from it when bitcoin is going down to $19k and moving up over $20k.
But one day suddenly the price will keep moving up and will not going to go back to the bottom they were expecting. In the mean time they sold the BTC at somewhere $20k to $21k. Imagine their face for selling early. LOL
Hodling is the best in any investment, if you consider Bitcoin as your investment then just HODL.
