Given the price of bitcoin skyrocketing, why would anyone spend it on anything. If you have 1BTC, and you think it's going to go up 100x still, then why would you ever spend it?
If USD is only decreasing in value compared to CHF why would you not keep everything in CHF? Because you need money to live from and you likely need USD to spend.
I only partially care if it goes /2 or x100. Its still money
