Emergency fund is not for investing, and even though guys can do whatever they like, they are going to be just putting themselves into bad situations if they are being reckless with their funds and investing with their emergency funds, especially if they have not figured out and/or establish their upcoming income, so if they have no expectations of future income, then it seems that there emergency funds are supposed to be being used to support themselves until such time as they are able to assure and/or secure future income.
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.
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.
That you have a steady source of income or an upcoming income that you are not sure of is not an enough good reason for anyone to invest part of or or from their emergency funds, emergency funds should only be used for the very purpose it is for because there is no smartness in trying to use it and buy Bitcoin with the hope of any incoming income that has not been confirmed and considering the fact that emergency can come unexpectedly in a manner of which we don't know to what extend it will cost and at such plans should be made ahead of time.
