I don't really like to play into arguments that rich people are more privledged, since anyone could come into a situation in which they have lump sums available and they are willing to dedicate some or all of that lump sum to bitcoin investing. For example they could 1) win the lottery, 2) inherit money, 3) have had been investing for 10 years and building their investment portfolio little by little (so they are not exactly rich, but they have been engaging in good savings/investing practices), 4) received a bonus at work for some kind of job they carried out (expected or not expected these kinds of things sometimes can happen to even less wealthy people), 5) they recalculated their various funds (emergency, reserves and float) and unexpectedly, they come to the conclusion that they have an extra $2k that they are able to invest 6) they received a gift from friend/relative/acquaintance and/or 7) a variety of other possible reason they could come accross extra money, whether that is some extra from their DCA amount or maybe it is a more modest amount
Exactly anyone can actually use lump-sum strategy depending on the individual condition though , and sir JJG have already given some wonderful example already , like winning a lottery, recieving a bonus at work for some kind of job they carried out etc. You can only say that the rich has more advantages when it comes to lump-sum purchasing, like most time due to having alot of cashflow, the money most rich are using may be higher than an average Man.
Surely the rich have advantages over the poor both in terms of the assets that they are likely to have and also the disposable income that they are likely to have; however, the mere fact of being richer than someone else neither means that investments into assets are going to be managed well or that the right kinds of investments will be chosen (such as into bitcoin), and so surely if we take a rich man and a poor man and we give them similar kinds of strategies, the rich man is going to have advantages, including that the poor man may well be able to catch up.
On the other hand, not all rich folks have good habits, so it could well be the case that poor people are able to catch up and even pass up some richer folks.. but sure, the poor folks still have to figure out ways to have disposable income, so it could well be really difficult for a poor man who is ONLY able to figure out ways to invest $10 per week into bitcoin to catch up to someone who ONLY sporadically invests $100 or $1k into bitcoin - but still the guy investing $10 per week is still doing better than the similarly situated guy who is not investing at all... .. and so yeah, we might choose ways to compare our own bitcoin investment performance to others or to compare our performance to other variations of ourselves, and there are likely going to be ways that the organized, persistent and consistent BTC investor is going to catch up, surpass and out perform other possible alternative scenarios.
If they are looking for short term profit then they will be disappointed and you are I know that for us to see reasonable profit in bitcoin investment we must invest for the long term and not short term. That's why it's necessary for people coming into bitcoin investment to have the right orientation/mentality. They have to know on time if are coming into bitcoin investment as a trader or hodler.
When it comes to knowing when to use the other two strategies like buying the dip or lump sum, well I will say that the person who is making his first buy in bitcoin can use lump sum buy and follow it up subsequently with DCA, especially if he wants to own a certain level bitcoin in his possession. While knowing when to use the buy the dip strategy is simply when you see the level of dip you have already predetermined or set for yourself before any dip occurs in the market. This will make you not to lose focus or confused on when to enter the market if eventually dip happens. You know nobody has the entire knowledge of the market and when certain variables will play out, so it's important to always get prepared before the eventuality of any market situation. When preparation meet performance, good result is always birthed.
Those who have spend time in Bitcoin have consent that it's ideal to invest into Bitcoin for long term. But that's not the case with new comers, most of them came with mind that Bitcoin is about getting rich overnight and when that desire is not fulfilled they get disappointed.
What you are saying is not exactly accurate, especially since people likely come to bitcoin with all kinds of perspectives and goals, and surely if someone has already been into bitcoin for a while, then that person may already be filtered out as more of a long term investor into bitcoin merely based on the fact that he continues to stay in bitcoin.
Regarding three techniques i.e. Lump Sum, Buy the dip and DCA, anyone with experience can adjust buy the dip and Lump Sum with DCA. If I am a new comer, I would prefer to go with small amount i.e. investing small amount every week or month. Once your confidence is developed you can go for Lump Sum with some increased capital. Both DCA and Lump Sum are good as long as you are confident about the technique you are adopting.
I think that you are still getting at the option of whether a lump sum is even available... so if there is a question whether a lump sum is available, then DCA makes more sense, but if a lump sum is available, then for sure there are more options, but it still might make a certain amount of sense to spread out the lump sum rather than investing right away, and if we go back to the example of someone who has an extra $3k... then there are so many ways to consider the matter, and it would seem short-sighted to completely ignore the availability of the $3k and to just DCA and buy on dips with it, since that would be presuming that the BTC price is either going to remain flat or to dip, so the more practical way of preparing for all price directions would be to use some of that $3k to buy right away, yet it is still a question of how much to use to prepare for up rather than preparing for down or sideways.. and each person has to live with their own decision, since there is not really any one correct answer, even though some answers (or approaches) seem more logical and reasonable than others... but people can still vary in their reason and also we might not completely know all of the reasons (the
9 individual factors) of another person without really knowing the person.
