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?
Dollar doesn't affect in bitcoin because this two are different asset with different value. Dollar is just an international convertion rate for bitcoin and other cryptocurrencies. For my own knowledge....If the dollar increase it won't give assurance that the value of bitcoin also increase. They are different.
Just the same dollar has an impact on Bitcoin, albeit indirect. If the dollar grows, you will get more in bitcoins. Well, in general, these are different "assets", I do not see a direct connection between them.
