Between USD and Bitcoin there is a relationship of value. Typically, Bitcoin is usually converted into USD. And most investors will use the dollar to buy Bitcoin speculation. So, if the dollar price drops, the value of Bitcoin will also decrease.
However, the rise and fall of the USD price did not significantly affect the growth or decrease of Bitcoin prices in the Cryptocurrency market.
True. Most of the deals involve dollar. Therefore, when this international currency falls, the price of Bitcoin can automatically go down. As you see, fiat and crypto are connected.
