Bitcoin has existed for more than 15 years now, and since from the inception, Bitcoin has shown to the world that investing in it is not just having a mere asset, but also about storage of value that appreciate with time, at no point has Bitcoin posed as a risky investment right from inception to those that have invested in it with, so this kind of narrative of Bitcoin being a risky investment was mongered during the early days of Bitcoin and over the years bitcoin has continued to prove those nay sayer's wrongly. If it's as risky as you make it sound, why would you even advise anyone to DCA in the first place, you shouldn't approbate and reprobate. there is no doubt about the fact that you should use your discretionary income while investing, however there are those that are financially buoyant who can also lump-sum not minding your narrative.
You just narrated things how they are, and even though bitcoin is a risky investment i don't think it is bad after all it has proven to stands a test of time so what else, risky or no risky we have all seen here bitcoin is today, they problem i have with people is that they will always have something to say even though there's nothing, some persons just keep coming up with excuses to discourage themselves, in life one must take risk although it should be a calculated risk, if I may ask what's even the risk in bitcoin investment that people talk about, an investment that we know that has an easiest way one can invest in it freely without stress, I think people refer hodling as risk, if not what then is even the risk here, I don't think anyone narrative should change anyone's mindset of buying with whichever pattern as far such pattern does not depend on buying only on dips alone.
