..I laugh and talk about Bitcoin to the owner of that showroom. I was surprised to that the owner of that showroom want to sell his phone to me for Bitcoin. And I asked him again, "Are you kidding me?"then He immediately gave me a bitcoin wallet to pay him. I paid him bitcoin and bought the Iphone 13 pro max.
Is BItcoin legal to be used as the payment method in your country? If yes, well that's good enough.
But if there is no law about that, it is always only between a buyer and also a seller. And everywhere, as long as they both agree, it doesn't matter, as long as the authorities there don't know about it (if there is a ban). If there is no prohibition, then just go on.
You can buy many of Iphone 13 pro max by selling 1 Bitcoin because it is expensive and its worth is equal to 20+ iphone 13 pro max and it is digital way to buy iphone 13 pro max using BTC as a payment asset.
You don't need to sell or spend all the whole 1BTC to buy that IPhone. And Bitcoin as a payment method is also a function of Bitcoin itself if available. So, it doesn't matter to use the BTC for payment. And the user has uttered what happen to his condition, so just be wise on your own ways.
As long as you are okay, why not if this can ease you do something. And if we are going to use BTC for trading or investing only, it also deosn't matter as long as we want.
