DCA is perfect but a little more stressful than any other strategy
I disagree with you that DCA is stressful than the other two methods of accumulating bitcoin. DCA is the easiest of them, because it allows you buy bitcoin with low amount regularly, all you need is to be discipline, so that you can be consitent and perdistent in accumulating, and growing you bitcoin portfolio. As long as you have sorted out the amount that you can use to buy weekly or monthly from you income, that wouldn't mount pressure on you, then you will invest in a comfortable way with rest of mind. It is when you fail to keep your emergency funds, reserve funds if possible, and the funds for your monthly expenses that it will become a stress, or when you over buy aggressively, without considering, if your emergency funds is big enough to withstand whatever emergency that occur. If you are use to saving money, then DCA accumulation strategy will be fun to you.
Lump sum pattern deals with accumulation of Bitcoin for future profits, basically a higher long term holding than any other strategy
All the three strategy serves the same purpose, which is to hodli for long, so that you can benefit from the compounding profit of your investment and also lower the risk attached to bitcoin investment. It sepends on the investor and the number of years that he plans hodling his investment maybe 4-10yrs abd above. Lump sum is good if you have the money to lump sum, as long as you are still buying regular with DCA method weekly or monthly.
Meanwhile buying the DIP means holding funds and always monitoring the market till when the price drops far below the last ATH
This is the most stressful of all and the most dangerous of all, for a newbie. This is because
1. Timing the dip id very difficult, and one might end up missing out when the dip comes, because he wants the price to be dipper than that. and night not know that is the bottom line of the dip.
2. During when you are holding your cash waiting for the dip, an unforeseen circumstance might occur that will make you spend that money or part of that money because you believe that you will be able make it up before the dip arrives, and the dip comes like a thief in the night.
3. Your cash will depreciate as you are waiting. However, buying at the dip is the best time to buy if you have the money to lump sum, when the market dips.
most investors who had enough money took the perfect opportunity and bought at that price
You can lump sum at the dip, because that is when you will get the highest profit, which is why many investors are buying large amount of bitcoin during the dip, and it shows from your statement that I quoted.
