yeap it affect alot
even the mandatory function of itself is the fee
If it hit $10,000 per bitcoin, the fee will be huge
If the price goes that high then I don't think that people would be worried about the fees and will be willing to pay even higher fees as they will start selling their coins and will convert to fiat as that is the only choice people have to spend their bitcoins.
Why go to Fiat? If the cost of bitcoin is very high, then the infrastructure will start to develop much faster. We will be able to buy everything using bitcoin. Fiat will be outside this chain
I don't get what you are pointing out ApplePanPine because the last time I checked the number of stores / online stores that accept Bitcoin is still limited even though Bitcoin is priced at 1200$ per Bitcoin. The point im getting at is that even though the price goes high up it does not mean that it will be instantly accepted anywhere. To prove it, the fact that Bitcoin is more expensive than any fiat currency out there but I am not seeing yet any physical store that is willing to accept it. And also they are right of converting their Bitcoin to Fiat because as of the moment Fiat currency is widely more accepted than Bitcoin.
