Why would you do that? Then, there would be nothing to be spent by you.
Just invest those you think you can afford and have something left for yourself and for emergency purposes. That is not how investing should be. It is suicide. Actually this is a dumb question but I think you need some light.
absolutely correct most especially because cryptocurrency is not that stable, there are ups and downs in prices and just incase there will be an emergency and need a big amount of money, selling of bitcoins right away is at risk. what i always do is 50/50 all the time, a half for bitcoins and a half for my daily expenses and for emergency purposes.
