Why not? Yes, of course I can. I don't see anything that makes cryptocurrency any different from fiat when it comes to them being used for exchange. It's the same thing. So, why not? Cryptocurrencies shouldn't be seen any different, in my opinion.

Again, if we talk of real estate it's almost like we're moving cryptocurrency; especially Bitcoin, from one state to another as it's also an asset. To be sincere, I see Bitcoin more of an asset than even a payment option. Moving it to purchase real estate doesn't make it lose its value.
