You seem to be getting over excited about your own ideas about what is poor, Justbillywitt. Of course, there is not just one level of poor, and some of us might be defining poor in different ways, and if we are defining poverty in different ways, then we might be arguing about semantics rather than figuring out thresholds in which it might be advisable or acceptable to invest into bitcoin versus not doing so.
You are correct that a person who cannot pay all of his expenses will not be able invest in bitcoin, since there is a need to have money beyond expenses and to be able to keep the money in bitcoin for 4-10 years or longer - otherwise with a shorter timeline, they would be trading/gambling with their money rather than investing... so not only does any person need to have discretionary income to be able to invest in bitcoin, they also need to be able to commit to keeping that discretionary income in bitcoin for 4-10 years or longer.
We likely realize that even poor people gamble with their money, so we cannot stop people from choosing to gamble with their money..
I am not going to try to proclaim to know all of the various levels of poverty, yet we know that there can be quite a bit of variance both in the terms of destitute that any person might have and the level of destitute will vary over time.. .so a person that is destitute may well have periods in which he has extra money that he could invest into bitcoin, yet it may well be unwise to invest, since he might not have any kind of confidence in regards to being able to continue to get income at various points into the future.
What I can say here is that. Poverty does not have a fixed state it can be fluid. Someone might feel poor because of high expenses or instability in his finances but that doesn't mean they are entirely knocked out of opportunities. There might be times when they have a surplus and times when they are only entitled to a small amount for consistent investment. My deepest concern for those in difficult states is the challenge for often lack of predictability. Even if they have extra money with them temporarily, their circumstance might make it unwise for them to commit to long-term investment especially when their future income is unpredictable.
Of course there can be questions about where to store surplus value when it is available and how much of the surplus value to keep in cash or in very liquid forms versus how much of the surplus value can be stocked away for longer periods of time, such as bitcoin's 4-10 years or longer category.
Does it mean this set of persons should not invest in Bitcoin?
The answer is somewhat individualistic in terms of their ability to put money aside that they would put into bitcoin and not touch for 4-10 years or longer, and surely in order to stop themselves from touching the money that they put into bitcoin, then they would have some cash buffers.. so yeah, if a person is living paycheck to paycheck and perhaps they have $400 to $500 per month income and $300 to $600 per month in expenses, then yes, they are poor and they ONLY have up to $200 per month of extra, but they have so much flexibility in their income as compared with their expenses, so that they already know that some months will be negative, so they have to have extra cash to cover those months, so they might not be able to invest into bitcoin until they have at least several hundred in dollars extra so that they know that they have their monthly expenses covered even if their income happens to be low that month. Each person will have to judge if he is able to invest in bitcoin and how much, and of course, it has to come from the extra income (the discretionary income) and if they and up making errors regarding how much extra they have, then they might end up spending from their bitcoin at a time that is not of their choosing, so they should be trying to set systems and buffers into place so that they are able to get through rough financial periods without having to touch any of the bitcoin that they would have had been able to stack aside.
If someone screws up or they do a good job in regards to how they choose to invest into bitcoin, that is their responsibility, so they are responsible to figure it out and also responsible for any consequences whether they make mistakes or if they end up choosing wisely, and hopefully they are figuring out strategies to be an investor rather than a trader or a gambler.
