nice article although this speculation is wrong that fiat currencies have no inherent value, all fiat currencies are backed by the issuing community i.e. public that they will exchange goods and services with it.

bitcoin and other crypto currencies like dash, monero, zcash does not have the backing of a community like ether or steem.

the only value bitcoin and similar currencies currently have is exchange value in a highly speculative market as majority of bitcoin transaction constitute of investment trading.
