investing money in bitcoin will be more good than saving it, if you are investing your money in bitcoin it will give you triple benefit, first your money will be in safe place, second if the price goes up the value of your money will also increase and the third that you can do online shopping using bitcoin more easily.
I agree to keep your money in bitcoin because of course it will be profitable. but I do not agree if you use all your money to be stored in bitcoin. however it is an investment and will always be at risk. not good if all your assets is in investments. so you have to have backup money in the bank or purse will be better
