But cryptos/Bitcoin isn't a currency in the traditional sense of the word so any analogies such as this are false?
A currency is the disposable medium of a defined economic entity - and its performance in terms of market pricing is determined by two things as far as I'm aware:
1 - performance and outputs of its native economy
2 - perception of the (strengths) of that economy relative to other economies in the world
I'm very new to getting my head around this but do not see any relationship with traditional currencies. In my mind the best comparison is with the gold indexes but there, again, there's a flaw in that, at least with gold there is an underlying base value.
So taking it one step further - its more like a gold derivatives index?
