@SuperBitMan you are correct to say that a person needs to have discretionary income in order to invest in bitcoin and not to be gambling with money that he needs for expenses, yet you are wrong to proclaim that the definition of poor is not having discretionary income. 

Poor is a much broader classification, and the person may or may not have discretionary income depending on the level of his poverty.

We use terms poor, middle class, rich in relative kinds of ways and even general kinds of ways, yet I doubt that it is very productive to get caught up in definitional arguments, when we might be able to clarify what we mean by either giving examples or describing the circumstances of such persons.

If you choose to categorize all poor people as those people who do not have discretionary income, then you are likely going to end up creating a lot of confusion, since there seem to be quite a few poor people who have some discretionary income or even quite a bit of discretionary income....  surely the more discretionary income that they have, the more possibilities that they have to bring themselves out of poverty.

Let's say for example that a poor person makes around $80 per week, and his expenses are around $60 per week, and with the remainder of his income around $20 per week, he likes to drink, gamble, eat ice cream (or other junkfood), perhaps smoke and to have fun with whatever spending money that he has.  If he chooses not to invest and/or save his discretionary income, he may never get out of poverty, yet he might have fun while his income is still coming in.   Sure, such poor person does not have a lot of discretionary income, and $20 per week is not going to be a lot of money to work with, yet it still falls in the category of discretionary income, and he might want to figure out if he can increase his income and/or decrease his expenses in order to increase his discretionary income...and yeah, he likely will not be living any kind of luxury life, and it likely would be really difficult for him to use his discretionary income effectively, such as buying bitcoin with half ($10 per week) and putting the other half into an emergency fund...

and yeah, he might sometimes have some unexpected shortfalls in his income or increases in his expenses that would force him to spend from his emergency fund, and surely we would want him to get to a level in which he does not have to draw from his emergency fund since if he depletes his emergency fund, then he will have no other resources left, except to dip into his bitcoin, which should be something that an investor is striving to avoid since the investor is wanting to use the bitcoin to make his life (and options) better in the future, perhaps 4-10 years or longer down the road.


There is a difference between investing aggressively and investing overaggressively, so yeah, a person with less discretionary income has less room to work with and they run more risks of investing overaggressively because they do not have as much money to work with in the event that they make errors in their calculations or if they have months in which their income is less and/or their expenses are more.


DCA can be accomplished in a variety of levels from whimpy to aggressive, and even overaggressive, so each person is responsible to figure out an appropriate DCA level and frequency in light of their own income and expense circumstances.


DCAing in bitcoin does not guarantee any kind of return, yet it does allow attempts at prioritizing investing in bitcoin on a regular basis in accordance with income and expense levels, and perhaps less likely to make mistakes of overinvesting (or underinvesting) if the weekly DCA amounts are incremental and building up over a longer period of time while the person is otherwise diligent about his personal financial and psychological circumstances..


You are reading too much into the dictionary definition.  That dictionary definition is general and does not go into considerations of income versus expenses or the management of cashflow, in order to get at various ways that a poor person might deal with his poverty, and potentially even be able to invest in bitcoin. 

Surely, we don't need a dictionary definition to tell us that there is variation in regards to level of poverty and also the particular circumstances of people are going to likely vary quite a bit in terms of some folks who are poor having discretionary income and others not having it.  Most people with an income are going to have some discretionary income, yet some people will have very low levels of discretionary income that it becomes impractical and even imprudent to buy bitcoin with that discretionary income, since maybe even some weeks they end up needing the discretionary income that they had from earlier weeks, so it would not have had been good to lock that money up into bitcoin..
