Not a rhetorical question, despite the flippant phrasing. I'd absolutely love to see crypto succeed, but it doesn't look like it's gonna be useful for white and grey market transactions any time soon. For those not familiar, the white market is the documented, above-ground economy, the grey market is the informal/unlicensed economy, and the black market consists of goods and services that are outright criminalized.
Using crypto for white market transactions would arguably defeat the purpose, but on the grey market cash continues to be king, even though this is exactly where you'd expect crypto to be useful. Gold and silver intuitively seem like a good option for grey market transactions, but they're way too traceable, and while the grey market is usually left alone, when the piggies do get sicced on a given grey market you're up shit creek.
Hopefully, but that's the optimist in me. DeFi could be great for businesses and assett transfer, but my favorite is monero. Monero would be awesome for grey market shopping.
