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.
No not to invest everything you have .You must invest a little bit and how about your expenses ?if you invest it all.Just invest the limit or excess on your money ,there must be a risky at investing but it also profitable when it terms in a long term.The price of bitcoin is flactuating and we did'nt know where it is high or going low but mostly I know it has a value that increases.
