Yes bitcoin is considered as savings, however in case of emergency you can not withdraw it immediately since you need to wait just to have a big return on your bitcoin.
That is right, if we will allot and will maximize our money and make a wise decision, we can have money that we can use in case of emergency, and I tried it last year, I am just thankful that I have enough savings when my partner in life admitted to hospital, good thing we are making wise decision all the time.
