You want him to swap absolutely scarce Bitcoin for something that can be printed infinitely out of thin air? Swapping to dollars would be the risk here.
Only since crypto boom I see people (crypto aficionados) thinking of money as an investment. And that makes no sense, as you explain yourself.
Dollars are much less volatile and thus less risky than any crypto currency I know. A perfect intermediate step before investing in some equity or some other thing that produces value.
I think it makes sense to consider money as an investment. Its somewhere you're deciding to hold value. Holding cash is a bad investment due to inflation so you need to spend it or store the value somewhere else. Its one of those things where deciding not to invest your money somewhere is a decision to invest it in money.
You know what else is absolutely scarce? Litecoin. And Solana. And XRP. And Cardano. And Avalanche. And Chainlink. And Bitcoin Cash. And Tron. And Ethereum Classic. And Stellar. And VeChain. And AlgoRand. And an infinite amount of other coins that anyone can invent at a moments notice.
Bitcoin only has value because someone else is willing to pay for it. That can hold true until it suddenly doesn't. If Bitcoin disappeared today, the world would go on without blinking. Nothing would stop functioning. That is of how little use it actually is.
That said, I'm a great believer in the meme value of Bitcoin and the greater fools. I hold several, with the belief that someday enough other fools will pay me a lot more fiat money to allow me to retire in style.
