Your emergency fund cannot just be seen as a safety net because it protects your investment strategy from being disrupted by life's unexpected events and thats something to take seriously. When you invest money you might need for essential expenses, you are more likely to sell during downturns not because Bitcoin has failed but because they have no other option, that is why the sequence matters: secure your essentials, maintain a financial buffer and then invest only what you can genuinely afford to leave untouched for years, and doing just so removes much of the emotional pressure that leads to panic selling and allows patience and sound analysis to work together over the long term otherwise you will find yourself struggling emotionally alot.
If you do not have stability, it is an anxious conviction with a story.
Your emotional aspect is significant. Imagine two investors sitting in front of the same number on the screen being red. One has a cushion. The other one has 3 weeks before the landlord begins questioning him. And no chart can ever portray the distance between the two. Same asset. Same price action. Complete other psychological experience. However, the decisions made in those two states are not even comparable.
Bitcoin has a long-term bull market. Monetary properties, supply mechanics, network effects all multiply over time. But the case only works for people who've structured their life to not need the money they have put into it.
