To explain more, for e.g., we hear that the USD was backed by the convertibility of this currency to precious metals until 1971. Now, what are altcoins backed by such as Ethereum or Litecoin? Are mathematical calculations performed by ASIC miners any useful in the real world?
Why would you ever try to asked that? I think that is just for the back end developers of the coin in order to maintain the stability and robustness of their system that is used to protect their coins.
