An emergency fund is necessary for long-term Bitcoin investment. Someone may be so poor that their discretionary income is very limited and they save a small amount of Bitcoin for the future. It may be difficult for them to raise an emergency fund. They should try to diversify their income sources or increase the amount of income they currently have. Need for an emergency fund should be partially mandatory because you should take your Bitcoin savings to a level where there is a possibility of high profits for 4-10 years. Need for an emergency fund is much more important to perfect your long-term Bitcoin journey.
What you said is true, but in my previous post if we are at the beginning of investment of course we continue to buy bitcoin while learning about the right way to invest in bitcoin. Emergency funds are certainly needed because we can use these funds when we lose our jobs so we don't have to sell bitcoin for our daily needs.
Investing in bitcoin with a good pattern of course there are several patterns that are considered.
Preparation of a budget that can be spent or discretionary income.
Have a fixed income every month for the smooth running of the investment we make.
Avoid mistakes by learning to get closer to the investment we make.
Provide self-satisfaction if one day we reach the peak or the last stage in the purchase made.
