Who says it's tough love? These are human beings, and they've been put in a really frustrating position. Denigrating someone who buys nfts is an appropriate response. Especially if they did it with your money.
Honestly, I saw video game coins and though it was some ingame currency. Also, these types might overhear you talking about crypto/ntf and just assume you've bought into it.
Regardless, they aren't making these jokes for anyone's benefit but their own. Remove the ntf thing, and this greentext is just anxiety inducing for a lot of introverts.
