Emergency fund is not recommended for investing in bitcoin but no bad to use it because put emergency fund in bitcoin have potential in the future price keep increasing than hold in pocket only, not really difficult for withdrawing emergency fund when saving in Bitcoin due put or hold in exchange wallet and when emergency happening to us we can sell and withdraw to bank account without take 10 minutes. No one can't predicting when happening with something urgent for us and my opinion better put emergency fund in bitcoin investment and seems the same when have parent hold or save their money allocated for children education. Hold in the bank can make it double although we start investing when our children under two or three years and take at seven or ten years later. Its very important allocated our fund for children cost but effective when saving or put in Bitcoin.
No, @armanda90, you are totally wrong. If you keep your emergency funds in Bitcoin, that means you are not actually keeping the funds for an emergency, but instead of investing them, emergency funds should be kept in a fiat bank or other place except Bitcoin.
As long as you are saving your emergency funds in Bitcoin, you will always go straight to your Bitcoin when emergency cases occur and saving in Bitcoin is not a thing you should be selling all the time. Bitcoin is an investment you should live for a longer time and investing in Bitcoin you must have a purpose for the investment, but saving in Bitcoin for an emergency is not a good idea.
