To get started in bitcoin investing in bitcoin, all that is needed is discretionary funds. Sure it might be helpful to have a budget to figure out future ways to keep buying bitcoin.. but it is not necessary to have all those matters sorted out in order to get started investing into bitcoin, and yeah, you are correct, if a person fucks up and spends from money that he needs for expenses a short time later or even in less than 4 years, then he is not investing, but instead either trading or gambling.
you are very correct JJG, having a budget to figure out future ways to keep buying bitcoin might be helpful, but it is not necessary to have all those matters sorted out in order to get started with bitcoin, because It can delay the person bitcoin investment journey if he or she want to put everything in place before getting started with bitcoin. All the person need is discretionary income to start investing in bitcoin.
You are also correct JJG if a person fucks up and invest funds that is needed to settle his or her expenses that person is not longer investing, rather he or she is either gambling or trading. And that's not the right way to approach bitcoin, what a person needs to invest in bitcoin is his or her discretionary income and not funds that he or she needed to settle expenses.
Those investors that do not see emergency fund as important or necessary are likely to crash before they reach their final accumulation stage. Therefore no matter how much fund you have you still can not do without emergency fund because it's like a life span to your already accumulated satsh, in other for your investment not to gradually get eroded, because in your journey of accumulation you might come across some huddles which you might be tempted to temper your investment, but with the setting aside of emergency funds, you will successfully scale through that phase without touching your investment or if need be very little not selling all, unlike not having any emergency fund to back your investment up.
For those investors that knows the importance of emergency funds they don't joke with setting aside emergency and back up funds.
