Is there any properly secured money? Each type of money has its flaws and its advantages. For one, bitcoin is traceable to a certain degree, whreas a paper bill is not.
Sorry, it was rethorical. I wanted to point out that fiat money disappears all the time. I lose money all the time; it falls out of my pocket, I forget where I put it... However I have never lost any amount of bitcoin.
>Sometimes money just disappear
Are you talking about fiat money or bitcoin?
