Bitcoin is not something we might buy now and expect to become rich tomorrow. It is a long term investment, and anyone who wants to profit from it must be patient and not panic when the market falls. The fact is that Bitcoin price changes all the time, and this is normal. However, if you panic and sell quickly, you might lose more than you gain. Real investors realize this and remain calm when prices fall.
Buying bitcoin as an investment and then doing DCA once its falls, is a good tactic but good investments are those which are done at suitable times. We had 2 years of pure bear market and it was the best time to accumulate between 15 to 50K. Those who have invested money in bitcoin once it was below 50K, those people must be in good gains these days and still holding.
Now i would not ask anyone to accumulate bitcoin near the all time highs (specially those who do not have extra money) and in times where we know the cycle may end in a few months. For fresh investments, maybe one can wait for a year or so and then he can get better prices to get into bitcoin. For those holding bitcoin, they should keep holding and shouldn't sell early there is still chance that bitcoin may 1.2x to 1.5x from the current prices.
