If I started during 2016, you're right. But I was a "trader" losing some money during that time before I decided to invest only in Bitcoin. If I started to Dollar Cost Average during 2019, it's obvious that I would have less units in Bitcoin.
I was merely lucky to have decided during the right time if we consider my situation. I lost some of my savings during my days of "trading" shitcoins before 2019.
I have no problem with the idea of starting out with lump sum, but that is different from saying that you are waiting for dips, even if that may well be how you are thinking about the matter.
In other words as soon as you figure out that bitcoin is the one, then it is best to focus on accumulation of it, rather than waiting as a strategy, and sure, if you have (or had) a lump sum to start out buying bitcoin, then good for you.
Your proclaiming that you have a buying on dip strategy comes off as a poor idea for a strategy, including your assertion that it is a good idea to wait until 2026 or 2027, which is likely not a great strategy, whether for you, an admitted low coiner, or someone else who might be even more of a low coiner than you.
But, sure, you can do whatever you like.. and maybe your gamble will work out, rather than the more assured thing of stacking sats.
Nothing concerns a new investor with buying the dip, atleast starting with the lump-sum is reasonable cause the person may be very financially capable to buy a very huge amount at once for a start but waiting for the dip for a newbie that's yet to have anything or a reasonable amount of coins in their portfolio is not advisable cause at that point you don't have anything in your portfolio so why wait, waiting would make them miss out on lots of buying opportunities since Bitcoin is volatile atleast if the person started with the lump-sum they already have something in their portfolio and would profit when it increase however, like I said earlier waiting would make them miss out on buying opportunities, so it's not advisable, I hear people saying that buying the dip is a choice but then an investor should have a reasonable amount of Bitcoin in their portfolio held for a long period before thinking of using the buy dip strategy which simply mean that you should atleast be a holder before thinking of missing out on buying opportunities, left for me the perfect strategy for a newbie is the DCA regardless of whether people think it's a choice for investors to use whatever strategy they like.
