Yes, to borrow any fiat currency at the present time when it buys a certain amount of goods - houses, bitcoin, cars etc. Then pay it back latter with “debased”(diluted, weakened in purchasing power) currency is definitely a “short” bet on that currency. Because you know that same $amount of borrowed currency will buy much less in 5,10,30 years. Most people think they are just going “long” on the asset.
I have a mortgage on my house… I’m not in a hurry to pay it off. I just sweep any leftover money into regular small purchases of BTC 🙂
