If you're worried to the point where it affects your health, it means you're in to heavy. If it's just concern, well, that's completely normal with any kind of investment.
I think if you are that worried you are taking it to the extremes then i think that is so dangerous. I think you don't need to take that far too much since we all know that digital currencies do not go at the same way and it always changes it price. It is volatile so the price do not stay in the same high price but there are time that it will be going down. Better rest it easy and start doing other stuff like altcoins.
it's better not to take high risks and what you can not do. because it must be measured by our ability. if you force the will to fear you bus fail. so measure something according to ability.
