Even though an investor doesn't have a good income source to keep a reserve and float funds, it is okay, but the investor should always make provisions for emergency funds, even if he has to reduce the money he will be using to accumulate bitcoin weekly or monthly just to build up emergency funds. It is important to have emergency funds when investing in bitcoin so that if any emergency happens, you will have what to use to settle the emergency and not depend on your bitcoin portfolio to solve it.
Exactly one of the reason I strongly preach against lump-summing as a formidable technique when accumulating bitcoin. Lump-summing could lead to aggressive accumulation that may affect other areas of your finance. People should always know that, inasmuch as your investment is necessarily important because it takes care of your long-term goals, there are also short-term goals one needs to meet, it could be from getting groceries to paying some bills at home.
Every strategy for buying Bitcoin is unique and solely depends on the investor in terms of his financial situation, risk tolerance level, investment goals and objectives (investment time horizon inclusive) the choice of strategies is not that really important to me but rather what is most important is how much of worth of Bitcoin do you have in your bag and how long can you be able to hold, I don't think if the Idea of lump summing has anything to do with being aggressive in your accumulation rather it has to do with buying right away with the available amount that is kept aside for buying Bitcoin, a man who has become knowledgeable about Bitcoin with so much believe can become limited in to investing in Bitcoin because of lack of finance, while receiving a huge amount of money can decide to to lump sum his first buying right away with the amount he made readily available to accumulate Bitcoin while other of his personal needs are already taken care of including emergency funds, while he may continues with dca strategy, there is nothing wrong being aggressive in your accumulation especially for a no or low coiner but it only becomes problematic when you are being overly being aggressive where it will affect your other needs. However, the combination of the both strategies can as well yield a better results. And, every investor must tailor down his choice of strategies that will suits him or her which will enable him in making an Informed decisions.
While you may be right at some point, when that man receives that huge sum of money and decides to invest everything due to FOMO or ignorance about the importance of having an emergency fund as well as a reserve for future emergencies amd expenses, and he decides to invest everything (lump-sum), would you not consider his actions or method as aggressive?
Let's properly look at that hypothetical scenario. A man has been studying about bitcoin investment and becomes too enthusiastic to invest in it without actually knowing everything about bitcoin, of course we already know that knowledge is limitless and you can never know everything no matter how much you know, you'll still have so much more to know. And in Bitcoin investment, there's just so much you wouldn't know until you've started your investment, those things studying wouldn't teach you all that, there are things you learn via studying and there are others you learn via experience so to gain the experience you need to be actively involved and utilizing the knowledge you've obtained over the years .
So let's assume the man in question have gathered lots of Bitcoin knowledge but has never invested before due to lack or limited funds and then all of a sudden, he receives $5k and without knowing that the importance of setting aside some money (Emergency Funds, Reserve and a float), or he's afraid on missing oitbon all the profits because during his waiting period, he's been seeing how profitable the market can be and how much he could've made if he had some good number of Bitcoin (FOMO) or simply because of just how enthusiastic or optimistic he has grown towards the market, he invests all $5k via lump-sum strategy, would you still still not consider his actions as not being too aggressive or still say you do not see any relationship between aggressive accumulation and lump-summing?
And yeah, every strategy is unique in their own way, it depends on the investors' goals and objectives. Trading is also a strategy that aligns with someone's goals and objectives, but you and I know how risky trading can be. Infact it's not even considered investing but gambling, yes it's still a strategy and it aligns well with someone's goals and objectives.
My point is that strategy matters a lot, because you could be using a strategy without really knowing the true potential of that strategy, simply because you feel it aligns with your investment goals without actually acknowledging the underlying risks involved.
Some strategies increases your risks of losses while some could relatively help you minimize those risks, sometimes without you even knowing about it. I'm not saying other strategies are not important, for the purpose of this study, they are important but there are strategies that are better regardless your goals, as long as Bitcoin accumulation is concerned.
Every strategies has it's prons and cons and there are several reasons for investors choice of strategies and there is no reason for this arguments or making any forms or comparisons. However, it seems that you are misunderstanding the Idea and concepts of the lump summing such that the fact that any investor will option to make the use of the lump summing as a strategy does not necessarily means that there was no provisions made for emergency funds or to have not taken care of his other needs and probably might not even be as a result of fomo. The Idea of lump summing has more to do with investing right away with a huge sum of money readily made available for investment after ensuring your other needs are taken care of including emergency funds which is Very important as individual even without venturing in to investment.
