.xyz didn't really take off. It's hard to tell whether it's because of general market conditions or the extension was simply hyped. Let's give it another year.
As for these names, I honestly don't see you selling any of them in the foreseeable future (few years at least, maybe never if extension goes sour). If you still believe in xyz - my strong recommendation is buying only names that could serve as brandables for all new markets: crypto, metaverse, the whole digi world of web3. Or one-worders nouns, mostly. And do not buy anything having less than 50 extension on dotdb, better 75 (your largest is 20, for these names). I don't think it will be impossible since a lot of people start to unloading their xyz portfolios. Just watch auctions and pending-delete.
Good luck!
