If you buy a dip in the Bitcoin market you can basically buy once. But investing time should not be wasted hoping to buy this dip as we have started investing here with DCA method. From JJG discussion we learn about long term investment, so we will mainly invest regularly in DCA method. So if we invest for the long term as a simple solution then our next holding portfolio will turn out.
At the first stage of investment planning, a new investor only thinks that he has to invest in Bitcoin. Before investing in a new situation, he has no idea that he has to hold his investment for a long time, but after investing, he gradually learns more detailed information about the investment. Very few new investors know about DCA method of investing. An investor invested 100 dollars in the first stage and later he thought to invest in stages but many investors do not know that this staged investment is considered as DCA method.
Those who have enough money and who have prior experience in investing can invest large amount of money at once as well as they can invest continuously but for those who do not have additional financial support DCA method of investment is a very effective method.
By the time we are discussing long-term investments, many investors may be selling their investments. For example, if I plan now that I will hold my investment for the next six years, then in 2030 it will be time to sell my investment. Similarly, those who held their investment for six years in 2018 will sell their investment in 2024.
I also have a solution to the issue you mentioned about waiting. If the investor has enough money, he will keep some money aside for the period when the market will come down a lot, but he will invest the remaining money consistently. If the investor plans in this way then I believe he will be able to make use of the opportunities that come along with investing consistently.
