This is extremely important as I can relate before. Always have extra funds, emergency funds. Because in the Bitcoin market, always expect the unexpected.
We can expect a lot from our investment but we must not forget that many things can happen in our life and by that, we must have extra, emergency funds like you said. We need them for what we don't expect but if it comes, we can solve unexpected situations well enough.
If we are not well prepare for unexpected situations, we will have very big trouble.
I experienced this before when COVID-19 started, we saw a huge dump there, and everyone must remember it.
The massive dump shortly after World Health Organization announced that it is a pandemic and named it as Covid-19 in March 2020, is unexpected situation. Thank you for recalling it as a reminder for extra plans in our investment capital and general financial management.
