...Since the price of Bitcoin has come down a lot now, it has become foolish for me to buy the phone with Bitcoin. Because for that I have to spend more bitcoin. But still I am very happy to be able to do it. Because in my country Bitcoin is still declared as an illegal currency. Nevertheless, I got this advantage
What matters to you most is securing the iPhone 13 Pro at that moment which you have successfully done, whether btc price is down or later will be up should not matter much to you now, but I don't think I will spend my hard earned btc buying iPhone, not just yet, perhaps when btc gets to a certain price level maybe.
Congrats on your first-ever btc purchase (which I believe it is) hope the device gives you the satisfaction and worth it.
