Bitcoin has a price cycle that repeats itself every 4 to 5 years and if you can wait for 4 to 5 years then you will get good yield on your money. If one has patience then he should go for 10 years investment plan, like keep buying Bitcoin for 10 years in case there is no huge money or invest huge capital as lump sum and wait for 10 years. If we go back 10 years then we can see that price of Bitcoin was under 500$ in 2015 which is nothing compared to current price of Bitcoin. DCA is most liked and followed because everyone can adopt that with ease.
It seems to me that with bitcoin there is a much better plan to supplement any lump sum buys that you do with ongoing DCA rather than just sitting around and waiting for your lump sum investment for 10 years. Many folks are not even able to lump sum and wait around, and many times they also don't want to lump sum, but they are actually practically sometimes able to lump sum a certain amount and they might even be able to front-load their investment over a year or two so that they are mostly in after a short period of time rather than investing over a whole cycle or two.
It tends to be way more practical for a lot of people to directly invest via DCA for a cycle or two rather than lump summing or being able to front load their investment into bitcoin.
I feel like a bit of a hypocrite making these assertions, since I do consider most of my bitcoin investment to have been during my first year and then supplementing a bit more over the next year and a half, and then at that point I went more into maintenance mode rather than accumulation mode... so an overwhelming majority of my BTC accumulation was done over two years...and even most of that accumulation was more heavily weighted in my first year investing into bitcoin... but it was mostly a front loading and taking various lump sum amounts from other locations and investing those amounts in to bitcoin in a hybrid DCA kind of a way.
Anyone who is new to Bitcoin or haven't invested anything into Bitcoin might not be interested in investing huge capital as Lump Sum, no matter how much money he has. It's a matter of time before new comers (or no coiner) thinks that it's fine to go investing Lump Sum. During that phase it's perfectly fine to go on with DCA.
Once you got yourself familiar with bitcoin then investing Lump Sum looks great specially on current dips. I personally think that those who want to go for Lump Sum and also looking for dip then current price of 83k is an ideal price for such people.
About your 10 years ago investment strategy, that's why I said that anyone who can invest today and wait patiently for 10 years will get good yield. Who knows 10 years from now, Bitcoin might by over one million USD.
Eid Greetings to all Hodlers !!! There is nothing wrong if a low coiner or no coiner wants to buy bitcoin with a lump sum strategy. There are low coiners or no coiners who can decide to lump sum at the early stage of their investment so that they can accumulate a reasonable size of bitcoin before they can start accumulating bitcoin consistently with the DCA strategy. You are misunderstanding the concept of a lump sum strategy. The concept of a lump sum strategy is not about waiting for a dip before you can buy bitcoin with a lump sum, but it is about buying bitcoin with a large amount of money right away when your lump sum money is readily available, even though the price of bitcoin is high or low at the time you want to lump sum.
