You would lose money if you're going to convert ALL your money to bitcoins.
I think that it's not only risky but it's also impossible to survive with all your money converted to bitcoins. Every day, you have to spend money on food, transportation, and shelter. Okay, some might be exempted for the expense of transportation if they do work at home and have no social life. Some might even be exempted in the shelter expenses because they might have bought the house before or that somebody else is paying for it. But food? You would always pay for your food. Even little kids need money because of food. It's still possible that you're still living with your parents and you don't pay any of the three. (That's pathetic, btw) but you are still going to eventually pay for something. You would eventually want to buy something and that leaves you to having to convert your bitcoins back to fiat money. That's a loss for you since the sell rate and the buy rate are a lot different. Not to mention that there's a cash out fee for all websites that allow you to cash out.
