Not necessarily bro, it's very fine to keep it in a financial system that doesn't experience much volatility, it would've been best in Bitcoin but the volatility is a great problem now.
For people with currencies that crashes against the dollar, they can keep them in stable coins like USDT to reduce the impact of inflation on it or you can even place it in the save option in a microfinance Bank app so it's there getting you little profits while you can break it anytime emergency comes.
If you convert your emergency fund into Bitcoin or buy Bitcoin with the money from your emergency fund. If an emergency situation arises, do you mean that you will sell that Bitcoin to deal with the emergency situation? If you mean something like that, then this is a completely wrong decision. Because suppose you have bought Bitcoin with your emergency fund money. If your financial crisis shows up and the Bitcoin market falls. Then where will you get the money to deal with the financial disaster? For all these reasons, it is never right to keep an emergency fund anywhere, it is always better to keep an emergency fund in cash.
I think you actually got the point right, but my question is that how does someone try to convert his emergency or reserved funds into Bitcoin, then I must say that fellow doesn’t know what investing in Bitcoin is all about and also having a good strategy to sustain our Bitcoin investment, by the way we’re not meant to invest in Bitcoin with our emergency funds or money for our expenses like our weekly or monthly income money, those are obviously not meant for buying and investing in Bitcoin, what is needed to invest in Bitcoin is a discretionary income, so we don’t mess up our Bitcoin portfolio which is basically meant for Bitcoin, and again emergency funds are not meant for finding solutions to our financial crisis, that is why we basically have a reserved funds, I don’t know if you have heard of reserved funds, that is a money that is meant to solve little details of our financial crisis should in case we find ourselves in an unforeseen financial situation, until we find our financial sustainability back, but we would have to start them 3 months into our bitcoin investment.
but I think the part that might confuse people is how you separated emergency funds from reserved funds. In financial planning terms, they are usually considered the same thing that is cash set aside for unexpected needs. If we start introducing another layer like reserved funds, it could give beginners the impression that they need to maintain multiple categories before they even think about Bitcoin, which might not be realistic for most people.
What actually matters is exactly what you pointed out, is that Bitcoin investment should come only from discretionary income, not money that is supposed to keep you afloat during emergencies. The clearer we keep that line, the less chance that people will end up mismanaging their finances in the name of stacking sats.
