In all the cases above I posted about them being fads, I remember arguing about vr domains with someone namepoos way back and I bought one vr domain, VRStick.com and I sit on it to this day to remind me to keep away from the fads.
,ai and .io and .xyz are all temporary
Can you make money on temporary?
Yup, just don't pay for inventory you can't sell later.
FWIW, of all the domains in my (albeit small) portfolio, the domains that get the most purchase inquiries (2022-2023 time frame), by far, are my one-word .ai domains. Haven't sold any of them yet, but I sure hope to. Majority of my portfolio is .com and I have no plans to change that.
It was the perfect storm - COVID created an everyone-work-at-home/no vacations scenario, thereby having bored people online all day, and this really helped drive digital items and other collectibles right through the roof.
There were big bags of money just waiting to be spent for stupid crap online, that otherwise would have gone to traditional outlets like restaurants, stores, vacations, etc. It was truly an insane time, and a perfect opportunity for scammers.
But now that people are "out and about" some (like NFTs) are dead while others (Pokemon/Sports/etc. cards) are continuing to drop back to pre-COVID levels.
