Turning all your money to Bitcoins is definitely a risk. Moreover, you cannot survive without fiat currency. This could be possible in the future but right now, it is definitely not going to work. Some companies are still not accepting crytocurrencies so how are you going to avail some goods if you do not have fiat currency in your hands?

On the other hand, Bitcoin price is not stable. We wouldn’t know what will happen in the long run. Only turn the amount that you could afford to lose.
