It should be in terms of mentality. I am also a type of person who will not be fully invested. Even now, there are still about 25% of my positions that are empty. Mainly, I hold long-term positions, so I am more like @ CryptoPainter_X and @ Murphychen888 M. These positions are mainly to deal with unexpected situations. For example, I was about 40% empty last year. In March last year, when the market fell sharply, I bought BNB at the bottom and have been holding it until now. Then, since the end of last year until now, I have bought some BTC spot whenever there is a decline, and have also bought about 10% of the position gradually. I have never sold it, and even saved most of my monthly income. If there is a final decline, I will go up again. If there is none, I will continue to buy on dips. Of course, different people have different methods, there is no right or wrong, all for the sake of making money.
