The key in 2 market cycles is having goals. In bear market, every market correction is a chance to buy and accumulate at lower price. This is where you split your capital for maximum profit potential for the next market cycle.
While in bull market, you set a goal on what price you willcliquidate your holdings. Remember that bear market will always happen so you should not be greedy in setting when you will sell your holdings.
That is why DCA exists. When you are in a bear market, you wait for it to fall, and buy some, if it falls more, you buy some more, and you keep doing that the more it falls. That is the way to grow, because you get a lot more bitcoins that way, and you drop your average purchasing price that way as well.
In return, you end up with profits, a lot of profits when the bull run starts and you just wait for that period. Don't sell right away when it goes to profit, wait for it to peak and you can sell a lot more. Like we have reached 100k+ , but during election period, we went from 30 or 40 something thousands, to more than 70 thousand, if you sold there, you would have lost %50 profit chance some more, and that's why you wait for peak.
