Is it a bad idea to use Bitcoin as a savings account?

I live in the U.K. and have a small amount of savings that I just add to each month when I’m paid.

Feels like a slap in the face that the BOE have told us all the accept that we are poorer. Despite how hard I work and how many hours I work a week.

Incase of an emergency I can just sell some Bitcoin if I need it?

What are the negatives?

I seen a post the other day about house prices and how even though they are more expensive it’s actually less Bitcoin to buy a house now then it was a few years ago. Logically it doesn’t make sense to hold GDP for big purchases or emergencies anymore does it?
