I can keep USD in a bank or money market account and get more USD out of it, just like I can for Solana or Ethereum. I'm currently earning like 3% on one of my accounts. It might not seem that way because we've had zero percent interest rates for so long and banks have had their rates at like 0.01% or something super low, but that doesn't mean it doesn't happen.
Also the value of the USD changes relative to other currencies all the time. There was a time where you needed 2 USD to get 1 British pound, but right now it's 1.25 british pounds for a dollar (i.e. the USD has increased in value compared to the british pound). There are people that make serious money just from trading between foreign currencies at the right time.
You mean if you invest your USD into a Money Market Account its able to generate a yield?
How can one sell a Money Market Account for more than they bought one for? The USD isn't generating a yield the Money Market Account is.

And if you advertise the GBP as a way for people to invest their USD on the premise that they can sell the GBP for more USD in the end I bet the SEC will not look fondly on you. There are also people that made bank on the stock market; doesn't make it not a security.
