Also, your stupid Cointelegraph said that Turkish Lira has dropped in value recently, but in fact it made a huge comeback as it went from $0.06 to $0.094
When even the USD would depreciate over time as the United State governments will manipulate it's price due to one reasons or the other. Fiats are depreciative in general. You are using fiat to compare fiat. Also that we like it or not, be it Lira increase in value lately or not, it's value over long period of time would not worth what it's price is today, it would depreciate.
The only thing which can determine the price of bitcoin is the dollar value.
No. You can use the fiat of your country to determine the price of bitcoin, not necessarily USD.
