Re: Money for nothing
sorry - but goods & services do NOT underwrite FIAT currencies.
Yes you can buy goods and services with crypto currencies - it's just not as common as most traditional, paper-based, alternatives.
It is all just a trust excercise & when trust in a currency breaks down it suddenly isn't worth anything. Take the Zimbabwean dollar for example, or for those with even longer memories the Yugoslav dinar, when trust broke down then hyper inflation kicked in which made that currency worthless.
Crypto currencies are just another form of currency, iwith no more or less real value than any other currency that is not tied to a physical commodity like gold. Each currency will ultimately succeed, or fail, only on trust and popularity.
