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, there is no direct relationship between the price of bitcoin and the dollar. They do not depend on the price of each other. Indirectly, it matters, because everything in this world should have a price ratio with each other. Therefore, if bitcoin grows in price, then more dollars are needed to buy it, and therefore it seems to be falling compared to bitcoin. However, this is at first glance, because the value of Bitcoin is simply taken into account.
