That's the usual way to "shill" a coin. Say something people would agree to and then say, well there is this one exception...

However, I believe that's not what OG was doing. Coins like the one he mentioned are used for illegal money transfers. So they actually have a use case unlike everything else in Crypto.

I thought Monero was going to grow in value in some kind of proportion to the term of Russian sanctions.

The total Monero market cap is too small to make a dent in any nations attempt to get around sanctions, but that would mean even a "small" amount of Monero use would pump its cap. And as its cap went up, its ability to process larger transactions would go up.

I still think that is valid long term reasoning, but the crypto market has so many different forces on it, so many hidden dynamics, that it's still better modeled as a casino than tech.

The cryptocurrency I "shill" can't be used for speculation in the buy and hold sense. The only way you can make money off of it is by making it less volatile and speculative.

Not at all! Monero is the only crypto that ever managed decent anonymity so I think it will continue to be used in illegal marketplaces even after the rest of crypto crashes. Some interesting security research being done in the Monero community as well.
