Also, I agree with supplementing lump sum investments with buying dips or DCA. Everyone is free to choose whichever strategy suits them best, especially if they are used to lump sums. However, I do think buying dips is a good approach, but that will depend on the portfolio status. It could be done similarly to DCA, but with opportunistic buys during price dips.
Buying the dips in a consistent manner like every dip we see, you'd buy is a good strategy. But the others are problematic on how to determine the dip when there's a dipper or lower that happens everytime the market corrects.
That is why that DCA is a good one that they can start with and they are not required to put any amount, any amount that they are free to do, they can simply do that.
TBH, if I have a huge capital that I want it back to the market and shall buy Bitcoin, I would do the lump sum style of it. So, if it's done then it's done. I don't have to stress myself out thinking when the dip will be. I'm good to go and will just have to watch how my holdings will go up as BTC increases.
