Yes, not every investor needs to invest in DCA method. Now not everyone can afford to invest a lot of dollars together. Assume that in my case it is not possible to invest large amount at once. So what should I do? Of course the best way for me is to invest in the DCA method.
The DCA method certainly has some advantages. If you invest in DCA method you can buy bitcoins at average price. Example you buy today at $98k may drop a bit after few days. Also, if you invest a lot of money together, it may be difficult to hold for a long time. You must save some cash for urgent needs. Now everyone has different strategies. The best way to invest in Bitcoin is to invest in the DCA method.
DCA is not the only strategy to invest in Bitcoin. There are different strategies for investing, and even different investors adopt different strategies for investing. Those who don't have a lot of money to buy a large amount of Bitcoin at once but have a fixed source of income can opt for the DCA method of investment. This method will be most helpful for them as they will buy bitcoins with fixed amount of money periodically and increase their investment.
I think the best advantage of the DCA method is that you can invest in bitcoins with little knowledge, and you can invest with a small amount of money and even buy bitcoins regularly.
If you buy bitcoins at 98 thousand according to today's market while continuing to invest in DCA method, when the price of bitcoins suddenly drops after a few days, you will have the opportunity to buy more bitcoins with the same amount.
