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.
yeah how can you afford of losing everything if all of a sudden bitcoin or this community collapse (just incase it happens but i surely not)what woukd you do or spent for recovery?nothing?then younwill end up crying because of what foolishness have you made?
As what the crypto words says.invest what you can afford to lose.it only means one thing dont invest all of your funds inside,but 50% is enough to make profit here most specially in bitcoin or ethereum that will perfectly increase prices sooner .
