Oscillating up and down, constantly inserting needles, have you ever been liquidated? The last one standing is the king. Bitcoin is the only winner in this casino. Holding for the long term is an investment with certainty. You can make money slowly, but you must be able to make money. After this bull market reaches its climax, sell a part of it, and then gradually bottom out in the bear market. Only when it reaches the next bull market cycle can you get greater returns. Repeat this over and over again. Money will definitely depreciate, and Bitcoin will definitely appreciate. This is an investment with certainty.
