You seem to be selectively quoting me in a way calculated to give the false impression that I said something obviously false instead of what I actually did say, which was obviously true. What motivates this extremely discourteous behavior?

Rebutting the grandparent's claim that Bitcoin was no more liquid than real estate was one of the main objectives of my comment. I am glad that you agree that their claim is obviously false, but I think it's unfortunate that you didn't respond to their comment to say so.

I agree that Bitcoin is less liquid than dollars, which is why I was making the exchange, actually. For other financial instruments, it depends on who you are, and whether you have an account with a stockbroker. You can't open an Interactive Brokers trading account with US$100, and it's going to be challenging if you are in Venezuela. You are going to have a hard time finding newsstands that will accept your SPY shares, but they are more liquid than Bitcoin in the sense that, given that IB account, you pay much less to convert them into dollars even if you have to cross the spread, and if you're willing to wait 20 minutes, you have an excellent chance of earning the spread instead of paying it.

But none of that compares for convenience with a guy handing me a US$100 bill.
