Surely back up funds can have different categories and even be loosely defined by some individuals, and part of the reason that I like to describe and differentiate three kinds of back up funds is in order to be able to show how they differ from each other, especially for someone who might be having to treat back up funds more seriously, especially if the back up funds might be for the purpose of protecting the bitcoin investment for 4-10 years or longer so that the bitcoin is not tapped into at a time that is not completely of the investor's choosing.
1) emergency funds are the last line of defense - so usually they should be at least for 3 months of expenses in local currency and used only for unexpected increases in expenses and/or decreases in income. Should be promptly replaced as soon as possible if used.
2) reserve funds - can be used for any reasons including emergencies, consumption, buying on dips or whatever reason.. optional whether to replace.. and surely the more erratic a person's income versus expense, then the more justification to keep more reserve funds.
3) floating funds tend to be the extra income that is held until monthly expenses are resolved.. once the monthly expenses are resolved, if there are any floating funds remaining, then those would convert into discretionary income that can be used to invest, consume or to add to back up funds (reserve funds and/or emergency funds)
The way you divided the back up fund into 3 parts is really amazing. I have never thought of it in such a specific way before. You have said that having an emergency fund for 3 months is enough. Yes, I agree with you. Many people want to have an emergency fund for 6 months or 1 year, I don't think it's necessary. It is enough to have an emergency fund for 3 months. If someone, like you said , divides their money into 3 parts and saves it according to the theory of reserve fund and floating fund , then they will be able to continue investing in bitcoin, avoiding all kinds of obstacles in continuous investing, in any kind of situation. Investing in bitcoin consistently is one of the ways to get good feedback in the future. Now I want to know one thing, that is if someone has the mindset that I will invest in bitcoin regularly every month for the next 5 years.
So will he fix a specific amount that I will invest 20% of my income in bitcoin ..or will he buy a specific amount of bitcoin regularly….. for example 0.0000085 bitcoin can be bought for 100$. Will he fix it that he will buy bitcoin for 100$ or 0.0000085 btc regularly, no matter what the price is.
It all depends on your discretionary income and not your income mate. After you have received your monthly income, you are to take out money for your monthly expenses and basic needs. The leftover is your discretionary income, that's is the money that you are yo use part of it and invest in bitcoin.
You cannot buy a fixed unit of bitcoin 0.0000085 because bitcoin price fluctuates. If not, you will put your bitcoin investment at risk because you might invest beyond your discretionary income when the price of bitcoin pumps higher than what you bought. For example if you bought 0,0000085btc at $100 when bitcoin price was at $108k and now that bitcoin price is $117k, if you want to buy the exact quantity, the price will be above $100 which is more than what you budgeted for. At the end since $100 is your discretionary income, it will lead to you selling your bitcoin too early when your basic needs arises because you bought with part of the money for your important needs.
However, having a fixed amount in which you can use to be buying bitcoin weekly from your discretionary income is the best as long as it is an amount that wouldn't put pressure on you. That will enable you continue buying every week consistently and persistently for 4-10 years and above till you reach your bitcoin target. Even at this, there are some weeks that you wouldn't be able to buy with the same amount from your discretionary income due to increase in your monthly expenses. Some times, when your expenses is higher than the initial amount, it will affect your discretionary income which will make you reduce the amount that you will buy for that week and when your monthly needs and expenses his smaller compared to what it use to be, it will increase your discretionary income and you can also increase our DCA amount for that week.
