Nope, I have not did this and I'm also not planning to do this because its not smart and its also that there are way too many risks for me to do this.
to me as there is no risk to invest in bitcoin, as bitcoin is one of the most safest way of investing money but still i am not going to invest all my assets in bitcoin as i have to keep some with my self for emergency, although i still invest a good amount from my salary every months as i know that it will really give me a good profit in the end.
If you will get a bitcoin debit card then you will not need to keep some fiat as you will be able to withdraw your bitcoins anytime when you will need your money where bitcoin will not be accepted.
