without an emergency fund, Bitcoin volatility can force you into bad sells. Keep a cash buffer so you can ride out dips without touching your stack. Risk management is what lets you stay long enough to see the upside.
An emergency fund should be considered essential by anyone considering long-term Bitcoin investment and not wanting to disrupt their Bitcoin balance every time they need cash. However, I recommend everyone have a steady job with a regular income stream so they can manage it carefully, including allocating a portion of their income to an emergency fund and using the rest as capital to buy Bitcoin. Because this can provide two distinct benefits, some investors often increase their monthly income to increase their capital to buy Bitcoin, even though their emergency fund may remain the same. Therefore, such things must be planned and managed carefully so that when difficult times arise, we can still weather them with cash without sacrificing the Bitcoin balance we've accumulated over time.
Fair enough, the emergency funds is really a very important part of our bitcoin investment going forward, But I don’t think the recommendation you made that everyone should have a steady job with a regular income stream in bitcoin investment will really go down well, most especially to the newbies who are desirous to venture into bitcoin investment but don’t have a steady job with a regular stream of income yet, it will really seem discouraging and even misleading to them making them to believe that they can’t venture into bitcoin investment except they have a steady job with steady income flow, meanwhile they can easily invest and accumulate bitcoin once they are able to sort out a discretionary income to invest with. In as much as we all may strive for more in order to sustain or improve our investments going forward , having a steady job or a regular stream of income isn’t a criteria for bitcoin investment, in fact, the most important thing needed to go forward for your bitcoin investment is just a discretionary income to accumulate with, your financial status might not enable you to accumulate on a regular basis, but that’s not much of a problem as you can be able to accumulate bitcoin and hodl either on weekly or monthly basis depending on how your income flows and when you are able to sort out your discretionary income. The idea is to accumulate bitcoin and hodl for the long term goal no matter how seldom you do it, as far as you’re holding for the long term and not selling for a quick profit or panicking to sell whenever you notice a little downturn in the market. The emergency funds can also be gradually build and improved with time along side as you’re accumulating.
