So before investing in Bitcoin make a decision in such a way that you never have to sell your investment. Set a specific goal and keep investing until you reach that goal.
and because of that, someone who invests in bitcoin needs to have a stable income and also savings that they can use when they need money for emergencies. because when someone does not have savings and they need money, then what they will do is think about selling the investment they have made, even though the condition at that time could be that their investment is in a state of loss, and that is a big mistake.
investors from the start must think about how they can divide between their investments and savings, so that when they need money for emergencies, then the savings can be used for that, not selling the investment they have made which can cause losses.
That's why when think about investing for long term people need to settle first their financial capabilities and have a steady income since nothing will happen to their plans if they don't have good source that can generate them stable income since their investment with bitcoin for long term will fail with that. Also they should not get stressed out about the idea of having an emergency funds since it doesn't need to put a huge money on it instantly so that they would able to have that funds for important purposes. They can put some amount when they earn and with that for sure it cannot totally affect their investment. Proper planning especially separating between needs is important so that all plans will work well.
