there are also investors who use some of their Bitcoin to meet their emergency needs because their emergency funds cannot cover them. This is understandable because we often experience emergency needs that we must fulfill immediately.
Your investment shouldn't be use for an emergency funds because that's not it purpose, however just like in everything we do there most be proper planning which will guide you as you are progressing and helps you to identify the possible unforseen circumstances that could possibly arise in the future or along the line and from there you could possibly see the reason why it is important to have an emergency funds that could be suitable enough to prevent you from tampering with your Bitcoin investment.
However an investors who consider his investment as an alternative to withdraw some funds in other to take care of needs is not actually consider as a good investor because is obvious that the investment may likely failed along the line, so actually if your emergency is not suitable enough you could as well re strategize your accumulation pattern to fit in your capability instead of putting everything and later you start selling off your Bitcoin investment for other needs.
