What are the crypto that you will “never” sell because of their long-term value?

Even with the crash right now, which I don't think will stay "crashed" for long, I still believe some crypto projects are worth holding for the long run. Not just for price action but for real-world utility and because of actually having an underlying value, bringing something useful, or having cool technology behind them.

I'm not talking about meme coins or hype plays or selling some BTC to get Christmas presents, but tokens that you think will only rise in value later. For me, and it could be a hot-ish take, but I think proof-of-personhood is a real thing and will become important as AI grows. So for that, I still buy more and more World. There's also Chainlink, it's basically the data layer of DeFi, and ETH, which many people see as a foundation of the decentralized internet.

Otherwise, I really am curious, what are your "no-sell" cryptos, and why?
