If a Bitcoin holder wants to invest in the long term, he can certainly do so with a small amount of money, because he has to determine his investment amount depending on his income. But I would like to add something else where if an investor can invest $ 10, if he spends extra money such as sitting in the park, smoking, sitting in the park with his girlfriend, and all the unnecessary expenses or bad habits that cost $ 20, he can add the $ 20 equivalent to the amount saved from here to investing in Bitcoin.
Therefore, if he can invest $ 10 + $ 20, that is, $ 30, weekly, then at the end of the year, he will definitely accumulate $ 360. And if he is able to continue investing in Bitcoin in this way after ten years, he will accumulate $ 3600 in Bitcoin, so long-term investment is the only way to achieve success according to the DCA method.
You don't call what people do for fun as a bad habit or unnecessary things except when doing those things becomes a problem to others because as a man your responsibilities also includes taking care of your girlfriend or wife if you have one. Some people smoke due to the weather condition of where they live especially in an extremely cold weather so you can't call it a bad habit since if they don't keep their body warm, it can lead to pneumonia.
investing with $10 will depend on your major income and your discretionary income because if you earn higher, your discretionary income will also be higher if your expenses are lower. Even though bitcoin can be invested with any amount but you have to figure out ways of increasing your DCA amount as time goes on because just accumulating $3,600 in 10 years of your investment in bitcoin is too poor.
