It is difficult to know what is meant by considering bitcoin as a "disaster" or a "calamity" - since there are some folks who might not know how to consider their risk and/or to attempt to manage their exposure to an asset such as bitcoin in accordance with their own particular circumstances - because bitcoin could be a disaster/calamity for any of us if we end up over investing or even under investing. If we overinvest and then we leave our bitcoin with third parties or we try to earn yield off of our bitcoin, we may well find ourselves with way less bitcoin than we thought that we had or that we have some or all of our bitcoin locked up (bankruptcy proceedings or whatever).
-snip-I am also surprised by those who consider Bitcoin a "disaster" or "calamity" because Bitcoin is not here to destroy but to be a differentiator in the context of giving everyone freedom to the economic system.
That's why I have the view that intelligent people who have the ability to think above average and have financial capabilities should be grateful for the presence of Bitcoin as a transparent new concept.
So it seems to the case that anyone who is half way intelligent should be able to recognize and appreciate that bitcoin is an asset class that is not correlated to other asset classes; however, even half way intelligent people are either not spending enough time to actually look into bitcoin or they may well be mislead by various mainstream media accounts (garbage superficial misinformation) that is being spread about.. and it takes a certain level of "looking into the matter" maybe between 20 hours and 100 hours depending on the person, in order to really start to grock how bitcoin is differentiated (and therefore a new paradigm shifting discovery/invention) from nearly all other asset classes.. a kind of investors dream to have a non-correlated asset - even though still if people invest, they still have to figure out the allocation level that they would like to assign to bitcoin as compared to other assets that they hold (and for any prudent/reasonably informed person, the answer should not be zero).
In learning there are stages where each stage has its own goals that are interrelated.
Regarding risk, we can say that every business person is familiar with overcoming or managing a risk.
IMO, those who consider Bitcoin to be a disaster are very good at hiding the truth.
They surely might not have had assigned an appropriate allocation level, so if the answer is to get off zero, but don't necessarily over do it (or you do not have to over do it), then the answer should attempt to lead people towards figuring out a level that is sufficiently enough for them, whether it is 1% or 25% or some where between, and if they are going outside of those bounds, then they likely need to have had studied even more.. but any beginner with 20 to 100 hours of study into bitcoin, should be able to figure out an allocation level that lands somewhere between 1% and 25% and then figure out how to tailor how to get there in regards to their own particular circumstances.
My suggestion tends to be to DCA once you establish your accumulation target level, but of course, you can also supplement DCA with buying on dips and lump sum investing.. which likely take a bit more knowledge than a more strict DCA approach... a more strict DCA approach would largely just entail figuring out your own budget to such a level that you are able to feel comfortable dedicating a certain level of cash flow on a regular basis, whether that is $100 per week, or $10 per week or some other amount and frequency that has been determined to be sufficiently acceptable as the person will likely also continue to learn while investing into bitcoin and likely pay more attention week after week if they are increasing in their stake into bitcoin, even if it might seem to be a kind of small amount (especially in the beginning weeks and even years but the ongoing investment into bitcoin may well start to add up with the passage of time)... and if these strategies are set with some semblances of moderation, then there should be no reason to be panicking about your investment or even viewing such investment as a "disaster" or a "calamity".
