as we know, the dollar is now rising, from the rise in the dollar it turns out that the price of Bitcoin is also rising, so what I ask here is that this is related to the dollar increase? or just coincidence?
No, I do not think that the dollar exchange rate directly affects the price of Bitcoin. If dependence is, then most likely, minimal and purely external. The dollar can only display the price of Bitcoin in a regular currency, but does not directly affect the price of cryptocurrency. Dollar exchange rate falls, because of this, cryptocurrency does not increase in price. Simply because of the different price values, the amount of cryptocurrency that can be bought also varies.
