I did let myself get sucked up into it for a while, mainly because I found a group that wanted to develop their own projects and felt it would be interesting to join them and learn how to code smart contracts (and I did learn a decent amount about it).
I was never a direct part of any launched projects though, I mainly just sat in on their calls and helped the devs debug a few things when people got stuck on something.
As they got excited about various NFT projects, I usually got something to be part of the group and show my support, usually a cheap one (like $30 here or there), but a few times I did spend more than that stupidly (like $100-200). Thankfully nothing too crazy though.
I spend more on my board game hobby every six months than I did the entire time I was paying attention to NFTs. Other people in the group did go full degen sometimes though, and spent way too much on it. I tried to dissuade them from the worst of it, but there were some true-believers in the group, thought everything was an investment.
I also never put any new money into it, it was always with Ethereum I had already bought long ago cheaply, so while the coins were worth $1000+ at the time, they were like $40 when I bought it originally.
I still have all the NFTs I bought, I never sold any, and whatever I bought all went to zero probably. That's usually what I do, I just buy things and never sell them, unless I have to make space, and usually then I sell for a massive loss (like my board games, why do they have to take up so much damn space?)
I still maintain that smart contracts are interesting technology, and would like to see something more interesting done than using a Collectible Card Game model with pictures that tries to get people to spend obscene amounts of money for pretty much nothing.
At the time it did seem like more than that though, it wasn't just buying a picture like people like to claim, it was like buying a membership to a club. My local Pickleball club wants people to spent $1500 a year for their memberships also. But as it turns out most of those NFT clubs were more promises and vibes than execution (Bored Apes did seem to be one of the rare ones to actually pull off something that felt more like a VIP club, and do various in-person things with owning the NFTs). But I never owned any Bored Apes, just followed the news about them for a while.
At one point I wanted to create a decentralized game achievement system with it, kind of like existing achievements but you don't need to rely on a console system or the game itself to track it, you just have a digital and system agnostic trophy, generated and signed by the game so you know it's official, that you can keep as long as there are smart contracts, but like every idea that pops in my head, I eventually get distracted by other ideas.
