To survive in life, money is definitely needed, but I think the remaining money after meeting the basic needs of your family is definitely alive. However, there is no remaining or specific money allocation for investing in Bitcoin, there is enough level of investment that you can invest according to your ability. However, you should never see it as a burden, Bitcoin investment never asks you to invest more.
You will be interested in investing in Bitcoin according to your ability, but for it to last for a long time, you must use the DCA method. There is a calm strategy for investing in Bitcoin for both the rich and the poor, in which both new and old, rich and poor can invest here. So you should keep yourself busy only to buy Bitcoin.
You must not use DCA method, but whatever method applies to you at any point. We're in Christmas and most workers here receive handsome Christmas bonus attached to their pay, such a person can decide to front load with those benefits since it might be considered his discretionary income.
A poor person can hit a jackpot from lottery, or thereabout and have a lot of discretionary income at his disposal and in that case, it's better to lump sum rather than keeping the money and possibly ending up using it for unnecessary frivolities. At every point in time, it's very important to appraise yourself and determine the best accumulation strategy to employ in your journey as long as you don't get overly aggressive which is sometimes detrimental. The goal remains having more stashes of Bitcoin in your portfolio and hitting your accumulation target faster.
Why not? Because in the end everything can still be done and it does not mean that even poor people cannot do DCA because in the end as long as they can manage the income they have well in the end they can still do it even though maybe the nominal is not too big for DCA size.
