The idea of getting started does not necessarily mean that anyone needs to start by investing a lot, and the getting started causes them to have to learn more about how bitcoin works and where to get price exposure.
Most people should have some general idea about how much discretionary income that they have, so even a person who knows that they have $100 per week that they could invest into bitcoin, might decide to start with $20-$30 per week while they are investigating further into bitcoin, and maybe it takes them several weeks or even several months to get more comfortable that they feel more comfortable to increase their DCA amount to perhaps $50 per week, and after some time they might be able to figure out how to increase their income and/or to decrease their expenses, so that they have $150 or $200 per week that they could invest into bitcoin, but they might decide to increase their investment to $80 or $100 per week at some point later down the road.
I think anyone with the idea that investing in Bitcoin requires a lot of money and to learn all about how Bitcoin investment worls may be misinformed or has gotten the wrong knowledge because Bitcoin investments is one of the most less stressful form of investment because with the DCA, the ease to invest is already there without feeling pressured of any kind since you are investing with what you can afford at different periods of time and just like your illustrations, anyone can begin at any discretion so far as they are not affected in other areas so when we talk about investing same amount at different intervals of time does not really we can not increase or reduce our DCAing amount in the future when our source of income has appreciated or depreciated.
Bitcoin investment works with time knowing the fact it’s a gradual process investing using the dca and other strategy, dca is never a must an investor should buy aggressively always but rather it all depends on the available income at the moment. Allocating our investment as equal as our needs is wrong from my view because a time might come when such investor never care for reserve funds and it might affect the investment, the possibility of keeping our investment determines on our planning and target that’s why when people talk about owning much before investing I feel they don’t know what bitcoin investing is all about. From start it’s advisable anyone start with the little they have and continue investing till when they feel they’ve gotten to a balance level then they can increase but saying it’s a must I disagree.
