After reading your post i see that you are tackling two kinds of risk  .  one is health and the other one is risk of bieng caught by the authorities because you think that bitcoin are not yet legal on some countries  .

I agree on the first risk which was health because i sometimes experience to work hard just to earn more bitcoins , i do multi tasking doing several online jobs . i sometimes ate on inapropriate hours and sleeping late  but i dont agree on the second risk that you claim ,  bitcoin is already legal on most countries today    .  you can freely use it as long as its legal on your country  .
