yes, emergency funds is supposed to act as a safety net whenever there is unforeseen contingency or situation that threatens ones peace of mind and not to be used for investing. so many fails to understand this and are easily carried away by the intense of making profits. However when they are face with emergency or situations that threatens there peace of mind that's when they will realise the importance of emergency funds, that it sole aim is not for investing.
this are the reasons why emergency fund need to be make available at all time, because emergency is an unforseen circumstance, which means that no one can tell when it will happen. So in no account should we think of investing from our emergency fund, and failure to this would result messing up our investment plans, probably when there's an emergency alerm at this point a guy will be running around looking for a way to figure things out without taping his bitcoin investment. And without the help of the emergency fund a guy May be finding it difficult, as there will not be any other alternative except his bitcoin investment.
unless one have steady source of income or upcoming income,if not using one emergency funds for investment is just like trading or gambling with one peace of mind.so it would be wise if emergency funds is strictly for emergency and discretionary income for investing in bitcoin.
I can only agree with you if the income is flowing every day, because without this, There's every possibility that a guy would surely face some difficulties in his accumulating journey, especially if you're a weekly earner, there are some emergency that May require immediate attention, in a situation like this a guy May not be able to hold on to it until his payday, so therefore having a steady source of income may not even be the best solution to that.
