Im just wondering. Bitcoin is so expensive. What if dollar value get low will it affect bitcoin value?
No it wont affect the value of bitcoin but it will affect on how much you can withdraw when exchanging bitcoin to dollar, bitcoins value is determined by its users worldwide trading market and dollar has its own trading market so both has different structures that affects its own price.
Personally, I did not notice such a connection. I trade in many currency pairs, but Bitcoin lives his life. I often saw when the price of the dollar is growing, at that time Bitcoin is also growing.
