Along with Bitcoin investment and immediately after forming an emergency fund, you have some more precautionary measures, if a person calculates and spends his daily expenses, then at the end of the month he will definitely save some money. And you can add this savings to Bitcoin investment by giving money and you can increase it even more by adding it to your current investment.
Sometimes someone doesn't need to do so many different daily tasks to increase there ongoing investment but instead they can use what they are getting from one to achieve what they intend because with determination it doesn't matter the amount provided that there would almost be a discretionary income for them after every measures of satisfying spending demands, because it will definitely be unhealthy when someone is going beyond the limits at which there strength could carry them in other to increase accumulation because if the person breakdown because of non resting it affects the consistency they were even maintaining on Bitcoin so actually the conclusion is that you can choose to increase your Bitcoin investment if there is an availability of more resources but don't over labor yourself for multiple job when you are already doing well with your current amount are putting in Bitcoin regularly.
Not everyone depends on one type of income. Some people earn only by physical labor, some people have online business, service sector or many other types of income. So if someone has physical and mental ability, then he can earn any other type of income if he wants. If he can increase the income path, it is definitely beneficial. For example, if someone's monthly income is $1000 and if he spends $700, then his discretionary income is $300. From here, if he wants, he will invest 200 per month in Bitcoin. Now if he creates a second source of income, if it is also $200 per month , then it will also remain as his discretionary income. And if he wants, he can invest the amount of his investment in Bitcoin, the previous $200 and the second income $200 together, to $400 in the DCA method. In this way, he will be able to achieve the over accumulation stage much faster than before. Apart from this, if he has only one source of income, then after losing his job, he may face major financial problems. If he does not get a new job very soon. So I think alternative income should be arranged.
